Dust Particle Counter, 2.83L/min, 0.3μm/1μm/10μm

The laser dust particle counter is a tabletop cleanroom monitoring instrument designed to quantify airborne particulate contamination. Powered by a long-life semiconductor laser source, it simultaneously detects six particle sizes and judges cleanliness grades from Class 100 up to Class 1,000,000.

Equipped with an integrated thermal printer, this unit prints full test reports on the spot. The intuitive 5-inch color touchscreen simplifies parameter setup and data review. It supports multiple particle concentration units and custom sampling schedules. Ideal for routine cleanroom audits, factory validation and laboratory particle testing.

Specification

Features

• 6 Synchronous Detection Channels: This laser particle counter simultaneously detects and counts air particles of 0.3μm, 0.5μm, 1.0μm, 3.0μm, 5.0μm and 10μm, supporting cleanroom particle monitoring and clean room classification ranging from Class 100 up to Class 1,000,000.
• Built-in High-Speed Thermal Printer: Integrated thermal printer outputs complete hard-copy air particle testing reports immediately after sampling. No external printer is needed for on-site cleanroom inspection.
• 5-inch Color Touchscreen: Equipped with an intuitive 5-inch color touchscreen, this dust particle counter features a user-friendly interactive interface for quick configuration, real-time particle data viewing and flexible parameter adjustment.
• 2.83L/min Sampling Flow: The built-in vacuum pump maintains stable 2.83L/min sampling airflow for reliable particle measurement. It allows adjustable sampling duration, sampling delay and multi-point sampling for clean room quality control.

Q&A

Q1: How to use this dust particle counter?
A: Place the unit on a flat stable surface and power it on. Run the self-cleaning cycle first. Set sampling duration, delay time and sampling points on the touch screen. Start sampling; the device counts particles and calculates cleanroom class automatically. Print the full report directly via the built-in thermal printer once testing completes.

Q2: How to replace the thermal paper roll of the built-in printer?
A: Turn off the particle counter. Open the printer compartment cover. Remove the empty paper core. Load a new thermal roll, pull out a small paper segment and keep it flat. Close the cover, tear excess paper, restart the device and test printing. Only use compatible thermal paper.

Q3: How to maintain the benchtop dust particle counter?
A: Keep the sampling inlet clean with lint-free cloth. Store in dry, dust-free location. Do not disassemble the internal laser module. Charge the battery regularly for long-term storage.

Q4: When should I calibrate the particle counter?
A: Annual professional calibration is recommended to maintain measurement accuracy. Replace thermal paper when printout fades. Contact technical support if readings become unstable or touchscreen malfunctions.
