The Particles Plus 8303 Handheld Particle Counter measure 0.3 to 25.0 um with a flow rate of 0.1 CFM (2.83 LPM). Easy to configure, these instruments display up to 6 user-selectable size channels as well as temperature and relative humidity. Particles Plus Counters can be controlled and monitored remotely via web browser. The mass concentration mode approximates density in ug/m and allows for density and refractive index corrections to ensure accuracy. All Particles Plus counters meet ISO 21501-4 and JIS B9921.
