The Series PMI Particulate Matter Transmitter is designed to measure indoor air

quality by detecting particulate matter in an ofce environment or HVAC duct. Using

laser scattering technology, the Series PMI can measure particles as small as 0.3

μm, making it an essential component of any indoor air quality monitoring system.

The optional relay combined with the settable alarm and control parameters allow the Series PMI to be a stand-alone controller.

BENEFITS/FEATURES

• Maintains healthy air supply with long term stability and accuracy

• Particulate matter application independent as duct and wall mount units are

available

• Low maintenance with 10 years of service life in auto mode

• Minimal downtime with overvoltage protection

• Easy setup with optional integral display and buttons

• Saves time using removable terminal block on duct mount model

• Single unit controller with alarm, control modes, and optional relay

APPLICATIONS

• Educational institutions

• Healthcare facilities

Indoor Air Quality Transmitters

• Corporate ofces

• Hotels/restaurants

• Air puriers
