Environmental Monitoring Solutions
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). 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® 8506-30 Handheld Particle Counter measures 0.5 to 75.0 μm with a flow rate of 0.1 CFM (2.83 LPM).
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® 5501P 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 2301P particle counter provides a range of particle size measurement from 0.3 to 25.0 μm at 0.1 CFM (2.83 LPM) flow. These sensors allow for efficient particle counting with high accuracy and resolution that meet or exceed ISO 21501-4 and JIS B9921 for the calibration of a particle counter.
The Particles Plus® 7501 Remote Particle Counter measures 0.5 to 25 μm with a flow rate of 0.1 CFM (2.83 LPM) and is the most versatile remote particle counter available. The 7501 can be used as a stand-alone battery operated instrument or it can be easily integrated into a building automation and cleanroom management system via Ethernet, or (optional) Wireless 802.11 b/g, RS485 or RS232.
