MONITOR INDOOR AIR QUALITY
The Series PMI particulate matter transmitter is designed to measure air quality by detecting particulate matter in an indoor environment or HVAC duct. It’s great for applications like schools, offices, and hospitals.

DEPENDABLE PERFORMANCE
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. It can function as a standalone controller with the optional relay. In addition, overvoltage protection prevents devices from failure and minimizes downtime.

EASY SETUP
The PMI has an installer-friendly design with a time saving removable terminal block for duct mount units. It also has an optional LCD and external buttons which simplify setup and use.
