9501 Remote Airborne Particle Counter
Particles Plus Remote Particle Counters
9501 Modbus
0.5 – 25.0 µm @ 0.1 CFM
The 9501 Modbus particle counter provides a range of particle size measurement from 0.5 to 25.0 μm at a flow rate of 0.1 CFM (2.83 LPM). These sensors allow for efficient particle counting with specifications that exceed the ISO 21501-4 and JIS B9921 calibration standards.
These sensors have 6 user-selectable particle size channels (up to 30 channels optional) 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.
