9301 ModBus

The 9301 Modbus Particle Counters offer a particle size measurement range from 0.3 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 ISO 21501-4 and JIS B9921 calibration standards.

These sensors come with 6 user-selectable particle size channels (up to 30 optional channels) and feature an integral critical orifice and flow sensor to deliver a stable flow rate from an external vacuum source. Integration into a building automation or facility monitoring system is straightforward via isolated RS-485 Modbus communication.
