Introduction
A dual-flow airborne particle counter is an instrument used to measure the number and size distribution of particles suspended in the air, with two sample flow paths that allow the measurement of particles at two sampling points or with two flow rates simultaneously, and it is used for cleanroom monitoring, indoor air quality assessment, and environmental monitoring. The particle counter operates by drawing air samples through the sensing volumes, where the particles scatter light from a laser, and the scattered light is detected and converted into counts and sizes of the particles, with the particles classified into size channels; the dual-flow design allows the measurement of two sample streams, which can be used for sampling two locations at the same time, for measuring with two different flow rates, for measuring both the total particles and a specific size range, or for redundancy, and the counter provides the particle counts for each flow path, with features such as data logging, alarms, and connectivity; the dual-flow counter is used for monitoring the particle concentration in cleanrooms and controlled environments, for assessing indoor air quality, for monitoring the performance of filters, for environmental monitoring, and for many other applications. Dual-flow airborne particle counters are used in pharmaceutical, semiconductor, and electronics manufacturing, in cleanroom certification and monitoring, in hospitals, in food processing, and in many other facilities where the particle concentration is important, and they are available as benchtop and portable instruments, with various size channels and flow rates. With their dual-flow capability, dual-flow airborne particle counters are versatile instruments for particle monitoring.

FAQ
Q1: What scenarios is this counter used for?
A: It supports two sampling flow rates for different cleanroom monitoring volumes and protocols in one instrument. It is used in laboratory, production and field settings, and our team can recommend a suitable configuration for your specific application.
Q2: What standards does it comply with?
A: It follows ISO 14644, ISO 21501 and related GB/T standards, with both flows calibrated. The relevant parameters are verified during final inspection before shipment, and compliance documentation or test reports can be provided on request for your quality records.
Q3: What is the warranty?
A: The counter carries a 12 to 24 month warranty covering the unit. Filters are consumables. Damage from misuse is excluded.
Q4: Is it hard to operate?
A: Operation requires trained staff for flow selection and classification. We provide a manual and training.
Q5: What is the lead time?
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 calibration required?
A: Performance should be verified periodically using calibrated reference standards, with results logged in the equipment record. Most users perform this check every 6 to 12 months or according to their internal quality schedule. We provide the procedure, reference materials and formal calibration service if required.
Q7: Are consumables universal?
A: Compatible items are single-use consumables designed for this application. They are widely available in standard sizes, and we can supply them directly or confirm the specification so you can source them locally. Ongoing cost is limited to these consumables, and there are no proprietary locked parts.
Q8: Can it be customized?
A: Yes, several configurations are available. Options include channels, data logging and telemetry. We can discuss further custom requirements, confirm feasibility and advise any effect on the schedule before the order is confirmed.
Q9: Is installation included?
A: The instrument does not need professional installation. After unpacking, connect it to the specified power supply, allow it to stabilize and confirm the self-check passes. The package includes a printed manual, and our support team offers remote assistance throughout setup.
Q10: What environments are compatible?
A: It handles controlled air within range. It is not for wet or explosive environments without rated design, or non-particle measurements.
