R2301P Remote Airborne Particle Counters

0.3 – 25.0 µm @ 0.1 CFM

The R2301P Particle Counters provideS a range of particle size measurement from 0.3 to 25.0 μm at 0.1 CFM (2.83 LPM) flow.

These sensors allow for efficient particle counting with high accuracy and resolution that meet or exceed ISO 21501-4 and JIS B9921 for the calibration of a particle counter.

These units are equipped with an internal pump and manifold and do not require an external vacuum source.

Integration into a building automation or facility monitoring system is easy via standard MODBUS RS-485 communication.
