Model 2501 and 2301 Remote Airborne Particle Counters
Brand: Particles Plus, IncThe 2301 and 2501 particle counters provide a range of particle size measurement from 0.3 or 0.5 to 25.0 μm at a flow rate of 0.1 CFM - 2.83LPM.
These sensors allow for efficient particle counting with specifications that exceed the ISO 21501-4 and JIS B9921 calibration standards.
These sensors have 4 fixed particle size channels and are equipped with an integral critical orifice and flow sensor to provide a stable flow rate from an external vacuum source.
Integration into a building automation or facility monitoring system is easy via isolated RS-485 Modbus communication.
