Introduction
An airborne particle counter is an instrument used to measure the number and size distribution of particles suspended in the air, and it is used for cleanroom monitoring, indoor air quality assessment, environmental monitoring, occupational health, and many other applications. The particle counter operates by drawing a sample of air through a sensing volume, where the particles scatter light from a laser or other light source, and the scattered light is detected and converted into counts and sizes of the particles, with the particles classified into size channels, such as 0.3, 0.5, 1, 5, and 10 micrometers; the counter provides the number of particles per unit volume of air, and it can also measure other parameters, such as the temperature and humidity, and it is used to monitor the particle concentration in cleanrooms and controlled environments, where the particle count is specified by standards, such as ISO 14644, and it is used for routine monitoring, for certification of cleanrooms, for troubleshooting contamination problems, for assessing indoor air quality, for monitoring the performance of filters, and for many other applications. Airborne particle counters are available as handheld portable instruments, which are used for spot checks, and as continuous monitoring systems with multiple sampling points, with features such as various size channels, data logging, and alarms. With their measurement of airborne particles, airborne particle counters are essential for cleanroom and air quality monitoring.

FAQ
Q1: What testing scenarios is this counter mainly applied to?
A: The airborne particle counter is used in cleanrooms, pharmaceutical manufacturing, semiconductor fabrication, healthcare facilities, food processing, industrial facilities, indoor air quality assessment, research and certification to measure the concentration and size distribution of airborne particles (typically 0.3 micrometer to 25 micrometer, in multiple size channels) using optical light scattering technology for cleanroom certification, environmental monitoring, contamination control and quality assurance. It supports cleanroom certification and monitoring (ISO 14644-1 classification, routine monitoring of particle counts in ISO Class 5-8 cleanrooms, aseptic filling areas, compounding pharmacies), pharmaceutical manufacturing environmental monitoring (viable and non-viable particle monitoring in GMP facilities, sterile manufacturing areas), semiconductor fabrication cleanroom monitoring (ultra-clean environments, ISO Class 1-5, sub-micrometer particle monitoring), healthcare facility air quality monitoring (operating rooms, isolation rooms, pharmacy cleanrooms, dental offices), food processing facility air monitoring (production areas, packaging areas, high-care areas), indoor air quality assessment (offices, homes, buildings - assessment of particulate matter PM2.5, PM10, allergen particles), industrial facility air monitoring (manufacturing areas, dust collection, worker exposure assessment), and research laboratory air monitoring. Airborne particle counting is essential for verifying cleanroom performance, monitoring contamination control, and ensuring compliance with regulatory requirements (GMP, ISO, FDA) in controlled environments.
Q2: What standards does the counter comply with?
A: The airborne particle counter follows relevant ISO, ASTM, IEST and GB/T standards for airborne particle counting, including ISO 14644-1 (cleanroom classification by particle concentration), ISO 14644-2 (cleanroom testing and monitoring), ISO 21501-4 (light scattering airborne particle counter - determination of particle size distribution), ASTM F328 (cleanroom particle monitoring), IEST-G-CC-001 (cleanroom operations), and relevant GB/T standards including GB/T 25915 (cleanroom standards) and GB/T 6167 (particle counter performance). The hardware complies with IEC 61010 safety standards. Calibration should use certified particle size standards (polystyrene latex - PSL spheres, traceable to NIST or equivalent) per ISO 21501-4. For pharmaceutical use, follow GMP requirements and 21 CFR Part 11 for electronic records (if applicable). Users should verify the specific standard for their application (cleanroom classification, indoor air quality, industrial hygiene) and the required particle size channels (e.g., ISO 14644 uses 0.1, 0.2, 0.3, 0.5, 1, 5 micrometer channels).
Q3: What is the warranty period for the whole counter and key components?
A: The whole airborne particle counter is covered by a 12-month warranty. The particle sensor (optical system, laser diode, photodetector), sample pump, flow controller, size discrimination electronics, controller, display, software and housing are covered, while calibration, filters (inlet, internal), printer paper, batteries (if portable) and fuses are consumables or accessories. Damage from improper use, sensor contamination (dust, oil, moisture), pump damage or unauthorized repair is excluded. Extended service contracts are standard for this cleanroom monitoring equipment (typically includes annual calibration, preventive maintenance, software updates). Laser diode may have separate lifespan/warranty terms (typically 10000-50000 hours depending on type).
Q4: Is this device difficult to operate? Is professional training required?
A: Operation requires trained personnel familiar with particle counting, cleanroom protocols, sampling techniques and regulatory requirements. We provide operation manuals, training and application support. Proper instrument preparation (calibration verification, battery charging, filter check), sampling location selection (per ISO 14644-1 sampling plan - number and location of sampling points based on cleanroom area and classification), sampling technique (isokinetic sampling, proper probe orientation, sample volume, sampling time), data interpretation (particle counts per cubic meter, size distribution, comparison to ISO class limits, trend analysis), quality control (zero count verification, calibration verification), regulatory documentation (certification reports, monitoring records, trend reports per GMP/ISO) and contamination control procedures are important for accurate, compliant particle monitoring.
Q5: What is the typical lead-time for order delivery?
A: Standard models require 7-30 working days. In-stock units can ship within 3-7 working days. Custom configurations or large built-to-order systems may require additional time, and we confirm the exact schedule before order confirmation.
Q6: Is regular calibration required? What is the recommended calibration cycle?
A: Calibration with certified PSL particle size standards recommended every 6-12 months (or per quality system - annual calibration is standard for cleanroom certification use, per ISO 21501-4 and ISO 14644-2). Routine zero count verification before each use (verify zero counts with HEPA-filtered air or zero count filter - confirms no background counts from sensor). Flow rate verification every 3-6 months (sample flow accuracy is critical - use calibrated flow meter). Full counter performance verification annually (counting efficiency, size accuracy, false count rate, flow rate - per ISO 21501-4). Laser output and sensor condition checked. Pump and flow system maintained per schedule. Software updates per manufacturer (for remote monitoring systems). For pharmaceutical use, follow GMP calibration schedules and maintain calibration records.
Q7: Are supporting consumables universal?
A: Calibration standards (PSL spheres - various sizes), inlet filters (disposable pre-filters for sampling in dirty environments), zero count filters (HEPA filters for zero verification), printer paper, data cables, batteries (if portable), cleaning supplies and fuses are available from cleanroom/laboratory suppliers, though filter type and calibration standards should match the counter. Long-term consumable cost includes annual calibration (primary ongoing cost) and occasional filter/battery replacement.
Q8: Can I customize parameters or supporting accessories?
A: Customization includes particle size channels (number and sizes - typically 0.3, 0.5, 1, 3, 5, 10 micrometer for standard; 0.1 micrometer for high-sensitivity semiconductor use), flow rate (1 CFM/28.3 L/min standard, 50 L/min, 100 L/min for high-flow models, 1 CFM is most common for ISO 14644), sensitivity (minimum detectable particle size - 0.1, 0.2, or 0.3 micrometer), portability (handheld/portable, benchtop, remote/manifold system for continuous monitoring), sample volume capacity, data logging, connectivity (USB, Ethernet, Wi-Fi, Bluetooth, wireless for remote monitoring), software features (cleanroom certification reports, trend analysis, ISO 14644 calculation, 21 CFR Part 11 compliance), printer, battery life, language and accessories. Additional probes, filters, calibration standards, tripods and accessories can be ordered separately. Custom orders extend delivery lead-time significantly, especially for high-sensitivity or remote monitoring systems.
Q9: Does the purchase include on-site installation and commissioning service?
A: Standard delivery includes the airborne particle counter and accessories with an operation manual. On-site installation, calibration and training are not included for standard orders but can be arranged at additional cost (recommended for cleanroom certification and pharmaceutical GMP use). Remote guidance is provided. Calibration should be performed by an accredited laboratory (ISO/IEC 17025) with a traceable calibration certificate.
Q10: What types of environments are compatible with this equipment?
A: The airborne particle counter measures airborne particle concentration and size distribution in cleanrooms (ISO Class 1-9, from ultra-clean semiconductor fabs to general cleanrooms), pharmaceutical manufacturing areas (aseptic filling lines, sterile manufacturing, compounding pharmacies, GMP facilities), semiconductor fabrication (wafer fabrication, lithography areas, ultra-clean environments), healthcare facilities (operating rooms, ICU, isolation rooms, pharmacy cleanrooms, dental offices), food processing (high-care production areas, packaging areas, ready-to-eat food areas), industrial facilities (manufacturing, assembly, paint booths, dust collection areas), indoor environments (offices, homes, schools, commercial buildings - indoor air quality assessment), and controlled environments (laboratories, test chambers, containment areas) within the particle concentration range, size range, flow rate and environment specification. Different environments require specific counter configurations: ultra-clean semiconductor cleanrooms (ISO Class 1-5) require high-sensitivity counters (0.1 micrometer minimum, high flow rate for low particle concentrations - need to sample enough air to count statistically significant particles); general cleanrooms (ISO Class 5-8) require standard counters (0.3 micrometer minimum, 1 CFM flow); industrial/dusty environments require counters with inlet pre-filters (to protect the sensor from high dust loading - do not use a standard counter in very dusty environments without protection, as dust can contaminate the optical sensor and cause permanent damage or false counts); indoor air quality assessment requires counters measuring PM2.5 and PM10 (typically 0.3-10 micrometer channels, with mass concentration calculation). IMPORTANT LIMITATIONS: Optical particle counters (light scattering) cannot distinguish particle composition (they count all particles regardless of material - they cannot distinguish viable from non-viable particles; for viable particle monitoring, use an air sampler with culture media in addition to particle counter); very small particles (< 0.1 micrometer) may be below the detection limit of standard counters (use a condensation particle counter - CPC - for nanoparticles); very high particle concentrations can cause coincidence errors (two particles passing through the laser at the same time are counted as one - use dilution or lower flow rate for high-concentration environments; verify the counter is within its coincidence limit); fibers and non-spherical particles may be sized inaccurately (optical counters assume spherical particles and report equivalent optical diameter - fibers may be counted as larger or smaller depending on orientation). Users should follow the specific sampling standard (ISO 14644-1 for cleanroom classification - specifies sampling point locations, minimum sample volume per point, number of points based on area and class; ASTM/IEST for routine monitoring), select appropriate sampling locations (representative of the cleanroom area, at work height, near critical operations, away from air supply diffusers - per ISO 14644-1 sampling plan), use proper sampling technique (isokinetic sampling - sample probe oriented into the airflow direction; allow proper purge time before sampling to clean the tubing; sample sufficient volume to achieve statistically significant counts - minimum 20 particles expected per ISO 14644; avoid sampling during personnel movement or operations that generate transient particles unless specifically monitoring those activities), interpret results correctly (convert counts to particles per cubic meter - particle count / sample volume in cubic meters; compare to ISO 14644-1 class limits for each size channel; calculate 95% upper confidence limit (UCL) for multiple sample points per ISO 14644; trend analysis over time for routine monitoring - look for increasing trends indicating contamination control issues), maintain proper quality control (zero count verification before each use - use HEPA zero filter; calibration verification with current calibration certificate; flow rate verification; background count check in the environment), and for pharmaceutical/GMP use, follow proper documentation (sampling records, calibration certificates, trend reports, investigation of out-of-limits results - OOS/OOT investigation per GMP; electronic records must comply with 21 CFR Part 11 if applicable). The counter should be handled carefully (the optical sensor is precision equipment - do not drop, bump, or expose to vibration; protect from dust, moisture, and extreme temperatures when not in use; store in a clean, dry environment). The sample inlet should be protected when not in use (use the inlet cap to prevent dust contamination). The counter should NOT be used to sample corrosive gases, flammable gases, or high concentrations of oil mist (can damage the optical sensor and laser - use appropriate pre-filtration or a specialized counter for such environments). For continuous/remote monitoring (24/7 monitoring in cleanrooms), use a remote particle counter or manifold system (not a portable counter - portable counters are designed for periodic sampling, not continuous use; continuous use can shorten pump and laser lifespan). Waste (used filters, calibration standards, printer waste) should be disposed of per applicable regulations (some calibration standards may contain PSL spheres in water - generally non-hazardous, but verify). The counter should be calibrated by an accredited laboratory (ISO/IEC 17025) at least annually, with a calibration certificate traceable to national standards (NIST, PTB, NIM) - calibration is critical for cleanroom certification and regulatory compliance; an uncalibrated counter cannot be used for official cleanroom certification or GMP compliance documentation.
