The 2501 particle counter provides a range of particle size measurement from 0.5 to 25.0 μm at a flow rate of 0.1 CFM (2.83 LPM).

The 9501 particle counter provides a range of particle size measurement from 0.5 to 10.0 μm at a flow rate of 0.1 CFM (2.83 LPM).

The 2301 particle counter provides a range of particle size measurement from 0.3 or 0.5 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 4 fixed particle size channels and are equipped with an integral critical orifice and flow sensor to provide a stable flow rate from an external vacuum source. Integration into a building automation or facility monitoring system is easy via isolated RS-485 Modbus communication.

The Particles Plus® 5301 Remote Particle Counter is the most feature-advanced remote particle counter available. Integration is easy into a building automation and cleanroom management system via Ethernet, or (optional) Wireless 802.11 b/g, RS485 or RS232.

The Particles Plus® 5301-AQM1 and 5301-AQM2 Remote Air Quality Monitor measures and displays particle mass concentrations for PM1, PM2.5, PM5 and PM10 including temperature, relative humidity, CO2 (and TVOC in the 5301-AQM2).

The Particles Plus® 5301P Remote Particle Counter is the most feature-advanced remote particle counter available. Integration is easy into a building automation and cleanroom management system via Ethernet, or (optional) Wireless 802.11 b/g, RS485 or RS232.
