The portable laser particle counter is a lightweight, portable testing tool built for mobile cleanroom particle sampling. Featuring a semiconductor laser sensor, it detects airborne particles in six size ranges.
Its compact handheld design lets technicians carry it easily between sampling points. You can store data onboard, export via USB, transfer remotely through WiFi, or pair with an optional Bluetooth printer to print test results immediately on site. Powered by a long-life 10000mAh lithium-ion battery delivering 8+ hours runtime, this portable counter is perfect for routine audits, on-site validation and field cleanroom checks.

Q&A
Q1: How to use the portable laser counter?
A: 1. Fully charge the device before use and power it on. 2. Let the instrument warm up for several minutes, then place the sampling inlet in your target cleanroom area. 3. Set sampling parameters including sampling time and location ID on the touch screen. 4. Start sampling; the unit will count particles and calculate cleanliness class automatically. 5. Save data locally, export via USB, or send to the optional Bluetooth printer for printed reports.
Q2: How to change the printing paper of the handheld laser particle counter’s Bluetooth printer?
A: 1. Power off the Bluetooth printer and open the top cover. 2. Remove the empty paper roll core. 3. Load a new thermal paper roll, pull out a small section of paper and align it flat. 4. Close the printer cover, tear off excess paper, then power on the printer and reconnect Bluetooth with the particle counter. Only use thermal paper for this printer.
Q3: How to read the dust particle counter results?
A: The touch screen displays real-time particle concentration for each size channel (0.3μm ~10μm). It also shows calculated cleanliness grade, temperature, humidity, sampling time and 95% UCL value. You can view particle histogram directly on screen, or export/print full data with complete sampling records for audit documentation.
Q4: What factors interfere with particle counter readings?
A: Strong local airflow, human movement near the sampling port, dust buildup on the inlet, corrosive gas, and unstable temperature/humidity will affect measurement accuracy. Let the device warm up and keep the sampling inlet away from turbulent air during testing.
