R9300P IoT Remote Particle Counter
0.3 – 25.0 µm @ 0.1 CFM
The R9300P IoT particle counter provides a range of particle size measurement from 0.3 to 25.0 μm at a flow rate of 1.2 LPM. These sensors allow for efficient particle counting with specifications that exceed the ISO 21501-4 and JIS B9921 calibration standards.
These sensors have 30 user-selectable particle size channels 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, TCP/IP over RJ45, Power over Ethernet, or WiFi (802.11 b/g).
