MET ONE BT-645 Benchtop Particle Counter

Overview

The Met One BT-645 is a compact benchtop aerosol mass monitor that measures particulate concentration up to 100 mg/m³ using a continuous-flow laser optical sensor. Combined with a purge-air system for accurate readings in adverse conditions, it is well suited to workplace, industrial-hygiene and indoor air-quality monitoring.

The BT-645 samples at 2 lpm with 1 µg/m³ sensitivity and stores over 28,000 samples, retrievable on the display or via computer with Comet software. A rechargeable Li-ion battery provides over ten hours of continuous operation, and RS-232/USB connectivity makes data collection straightforward.
