FAQ
Q1: What testing scenarios is this counter mainly applied to?
A: The portable airborne particle counter is used in cleanroom field certification, indoor air quality (IAQ) assessment, HVAC system testing, industrial facility management, building inspection, occupational hygiene, property management and field service to measure airborne particle concentration and size distribution on-site using a battery-powered, handheld instrument for convenient, location-flexible particle monitoring without requiring fixed installation or external power. It supports cleanroom field certification and routine monitoring (ISO 14644 classification verification, spot checks in cleanrooms, aseptic areas, compounding pharmacies - portable design allows testing at multiple locations and rooms), indoor air quality assessment (offices, homes, schools, commercial buildings - assessment of particulate matter, dust, allergen particles, post-remediation verification), HVAC system performance testing (supply air, return air, filter efficiency verification, duct leakage assessment), industrial facility air monitoring (manufacturing areas, warehouses, workshops, dust collection performance, worker exposure spot checks), building inspection and property management (pre/post-construction, mold/dust assessment, building science investigations), occupational hygiene field surveys (worker exposure assessment, spot checks in work areas), and field service and commissioning (HVAC commissioning, cleanroom commissioning, filter installation verification). The portable, battery-powered design allows rapid deployment in any location, making it ideal for field service, multi-site testing, and spot-check applications where a fixed or benchtop counter would be impractical.
Q2: What standards does the counter comply with?
A: The portable airborne particle counter follows relevant ISO, ASTM, IEST and GB/T standards for airborne particle counting, including ISO 14644-1 (cleanroom classification), ISO 14644-2 (testing and monitoring), ISO 21501-4 (light scattering airborne particle counter), ASTM F328, IEST-G-CC-001, and relevant GB/T standards (GB/T 25915, GB/T 6167). The hardware complies with IEC 61010 safety standards and applicable portable equipment standards (battery safety - IEC 62133 for lithium batteries, UN38.3 for transport). Calibration should use certified PSL particle size standards traceable to national standards (NIST, PTB, NIM) per ISO 21501-4. For cleanroom certification use, the counter must have a current, traceable calibration certificate. Users should verify the specific standard for their application (cleanroom, IAQ, occupational hygiene) and the required particle size channels (ISO 14644 uses 0.1-5 micrometer channels; IAQ typically uses 0.3-10 micrometer for PM2.5/PM10 calculation).
Q3: What is the warranty period for the whole counter and key components?
A: The whole portable airborne particle counter is covered by a 12-month warranty. The particle sensor (optical system, laser), sample pump, flow controller, battery, display, data logging, controller and housing are covered, while calibration, inlet filters, zero filters, batteries and fuses are consumables or accessories. Damage from improper use, sensor contamination, dropping, water damage (if not rated for wet environments), battery damage or unauthorized repair is excluded. Extended service contracts may be available (typically includes annual calibration, preventive maintenance, battery replacement). Battery may have separate warranty terms (typically 1-2 years or 300-500 charge cycles for lithium-ion batteries). Laser diode lifespan depends on usage (typically 10000+ hours).
Q4: Is this device difficult to operate? Is professional training required?
A: Operation requires trained personnel familiar with particle counting, sampling techniques, and applicable standards. We provide operation manuals, training and application support. Proper instrument preparation (calibration verification, battery charging, zero count check, filter check), sampling location selection (per ISO 14644 sampling plan or IAQ assessment plan), sampling technique (isokinetic sampling, probe orientation, sample volume, sampling time, purge time), data interpretation (particle counts per cubic meter, size distribution, ISO class comparison, PM2.5/PM10 mass calculation for IAQ), quality control (zero count, calibration verification, flow check), reporting (certification reports, IAQ reports, trend data) and proper field procedures (safety in field environments, PPE, ladder safety for high sampling points) are important for accurate, reliable field 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 standards recommended every 6-12 months (annual calibration is standard for cleanroom certification use per ISO 14644-2 and ISO 21501-4). Routine zero count verification before each use (verify zero counts with HEPA zero filter - confirms no background counts). Flow rate verification every 3-6 months (use calibrated flow meter - battery-powered pumps can drift). Battery performance check every 6 months (capacity test, replace when runtime decreases significantly). Full counter performance verification annually (counting efficiency, size accuracy, false count, flow rate per ISO 21501-4). Laser and sensor condition checked. Software/firmware updates per manufacturer. For field use, verify calibration certificate is current before each certification project.
Q7: Are supporting consumables universal?
A: Calibration standards (PSL spheres), inlet pre-filters (for sampling in dusty environments), zero count filters (HEPA), batteries (rechargeable lithium-ion), battery chargers, data cables, printer paper (if integrated), carrying case, tripod, extension probes, cleaning supplies and fuses are available from laboratory/cleanroom suppliers, though filter type, battery model and calibration standards should match the counter. Long-term consumable cost includes annual calibration (primary cost), battery replacement every 1-3 years, and occasional filter replacement.
Q8: Can I customize parameters or supporting accessories?
A: Customization includes particle size channels (0.3, 0.5, 1, 3, 5, 10 micrometer standard; 0.1 or 0.2 micrometer for high-sensitivity), flow rate (1 CFM/28.3 L/min standard, 50 L/min, 100 L/min for high-flow portable models), sensitivity (minimum detectable size), battery life (extended battery for all-day field use), data logging capacity, connectivity (USB, Wi-Fi, Bluetooth for data transfer to phone/tablet), display (color touchscreen, monochrome), integrated printer, temperature/humidity sensor (for IAQ - simultaneous T/RH measurement), gas sensor (CO2, CO, VOC for IAQ multiparameter), carrying case, tripod, extension probe/flexible probe (for sampling in ducts, hard-to-reach areas), language and accessories. Additional batteries, probes, filters and accessories can be ordered separately. Custom orders extend delivery lead-time.
Q9: Does the purchase include on-site installation and commissioning service?
A: No installation is required for portable units. The package includes the portable particle counter, battery, charger, zero filter, carrying case and instruction manual. On-site training is available at additional cost for cleanroom certification or IAQ assessment field work. Remote guidance is provided. Calibration should be arranged before field use (calibration certificate required for official certification work).
Q10: What types of environments are compatible with this equipment?
A: The portable airborne particle counter measures airborne particles in cleanrooms (ISO Class 5-9 for standard portable models; higher sensitivity models for ISO Class 1-5), pharmaceutical and healthcare facilities (aseptic areas, operating rooms, pharmacies, dental offices), food processing areas (production, packaging, high-care areas), indoor environments (offices, homes, schools, commercial buildings, basements, crawl spaces - IAQ assessment), HVAC systems (supply diffusers, return grilles, ductwork - use extension probe for in-duct sampling), industrial facilities (manufacturing, warehouses, workshops, paint booths, welding areas - use inlet pre-filter for dusty environments), construction sites (pre/post-construction, renovation, demolition - dust monitoring, use appropriate protection), and field environments (any location with access - portable design allows testing anywhere) within the particle concentration range, size range, flow rate, battery life and environmental specification (temperature, humidity, dust level). IMPORTANT FIELD CONSIDERATIONS: The portable counter is designed for field use but has limitations: battery life (typically 4-8 hours continuous use depending on model and flow rate - bring spare battery or charger for all-day field work; allow battery to acclimate if moving between temperature extremes - battery performance decreases in cold environments below 0 degrees C); dust protection (field environments may be dusty - use inlet pre-filters to protect the optical sensor; do not sample in very high dust concentrations without protection - can permanently contaminate or damage the sensor; clean the sensor per manufacturer instructions if exposed to high dust); moisture/condensation (do not use in wet or high-humidity environments beyond the rating - moisture can damage the optical sensor and electronics; if moving between cold and warm environments, allow the counter to acclimate to avoid condensation inside the instrument - wait 30-60 minutes before use); transport safety (use the carrying case to protect the counter during transport - dropping can damage the optical sensor, laser, and pump; for vehicle transport, secure the counter to prevent bouncing; lithium-ion battery transport follows applicable regulations - UN38.3, IATA for air transport); field sampling technique (use a tripod or hold the counter at proper height - typically breathing zone height 1.5 m for IAQ, work surface height for cleanroom; use isokinetic sampling - orient the probe into the airflow direction, especially for in-duct or near-diffuser sampling; allow purge time before sampling to clean the inlet tubing; sample sufficient volume for statistical significance - per ISO 14644 minimum 20 particles expected; for IAQ, sample 5-10 minutes per location for representative results; avoid sampling during active dust-generating activities unless specifically monitoring those activities - note the conditions in the report); data interpretation for field use (convert counts to particles per cubic meter; for cleanroom, compare to ISO 14644 class limits and calculate UCL per ISO 14644; for IAQ, calculate PM2.5 and PM10 mass concentration using appropriate density conversion (note: optical particle counters measure particle number, not mass - mass conversion assumes particle density and size distribution, which introduces uncertainty; for regulatory PM2.5/PM10 measurement, use a gravimetric sampler or regulatory-grade monitor, not an optical particle counter - optical counters are for screening/assessment only); note field conditions (temperature, humidity, occupancy, activities) in the report, as particle levels vary with conditions); and reporting (for cleanroom certification, follow ISO 14644-1 reporting requirements with sampling plan, data, UCL calculation, and pass/fail conclusion; for IAQ, provide location details, sampling parameters, results, interpretation, and recommendations; include calibration certificate number and date in all reports - uncalibrated counter results are not valid for official certification or regulatory compliance). The counter should be cleaned after field use (wipe exterior, check inlet for dust, clean sensor if needed per manufacturer, replace pre-filters), stored in the carrying case in a clean, dry environment, and the battery should be properly maintained (do not fully discharge lithium-ion batteries for long-term storage - store at 40-60% charge; recharge every 3-6 months during storage). For multiparameter IAQ models (with CO2, CO, VOC, T/RH sensors), calibrate the gas sensors per manufacturer schedule (gas sensors drift over time - CO2 NDIR sensors are stable but should be verified; electrochemical CO/VOC sensors have shorter lifespan 1-3 years and should be replaced when depleted). Waste (used filters, batteries, calibration standards) should be disposed of per applicable regulations (lithium-ion batteries are recyclable - do not throw in regular trash; PSL calibration standards are generally non-hazardous but verify).
