Product Overview

The HM-CL3 Desktop Airborne Particle Counter provides high-flow 28.3L/min (1cfm) sampling designed for fast and accurate cleanroom classification. In accordance with GB/T6167-2007, JJF1190-2008, ISO 14644, and GMP standards, it simultaneously measures six particle size channels (0.3, 0.5, 1.0, 3.0, 5.0, 10.0 μm) to reliably monitor airborne contamination.

Key Features

28.3L/min high sampling flow rate completes 1 cubic meter sampling in approximately 35 minutes.
Android 7.1 operating system paired with a 7-inch high-definition color capacitive touchscreen.
FDA 21CFR Part 11 compliant audit trail functionality with multi-level permission management and event logging.
Automated cleanliness level determination supporting ISO 14644, FS209E, and dynamic/static GMP standards.
Built-in temperature, humidity, and environmental air pressure sensors for comprehensive ambient data.
AC and DC dual-use with internal rechargeable lithium battery (220Wh, 16.8V/15Ah) supporting over 6 hours of continuous sampling.
Built-in thermal printer and driver-free USB data export supporting up to 100,000 internal test records.
