Environmental Monitoring Solutions
The 9301P IoT particle counter provides a range of particle size measurement 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 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, TCP/IP over RJ45, Power over Ethernet, or WiFi (802.11 b/g).
