9301P Remote Airborne Particle Counter

Particles Plus Remote Particle Counters

Model 9301P

0.3 – 10.0 µm @ 0.1 CFM

The 9301P particle counter provides a range of particle size measurement from 0.3 to 10.0 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 internal pump and manifold and do not require an external vacuum source. Integration into a building automation or facility monitoring system is easy via isolated RS-485 Modbus communication (other communication options available).
