HM-CL1 Dust Particle Counter

HM-CL1 Dust Particle CounterHM-CL1

HM-CL1
HM-CL1 is the entry-level benchtop model in the HM-CL series, sampling at 2.83 L/min across six particle size channels from 0.3 to 10.0 µm with automatic cleanliness class judgment, AC-powered operation, and a 7-inch Android touchscreen — the most cost-effective route to GB/T 6167-2007 and ISO 14644 compliant particle counting.

HM-CL2 Dust Particle Counter

HM-CL2 Dust Particle CounterHM-CL2

HM-CL2
HM-CL2 adds AC/DC dual-use battery operation, an FDA 21CFR PART11-compliant audit trail module and a built-in thermal printer to the six-channel 2.83 L/min measurement core — letting one benchtop instrument serve both the cleanroom bench and the field survey without external accessories.
HM-CL3 Dust Particle Counter

HM-CL3 Dust Particle CounterHM-CL3

HM-CL3
HM-CL3 is the high-flow benchtop model in the HM-CL series, sampling at 28.3 L/min (1 cfm) — ten times the air volume of the HM-CL1 and HM-CL2 per minute — with the same six-channel 0.3–10 µm measurement, AC/DC battery, FDA 21CFR PART11 audit trail and thermal printer, plus an external high-flow filter for self-purification, making it the preferred instrument for large-cleanroom ISO 14644-1 certification campaigns where the minimum sample volume per location must be collected in a single pass.
