Perkin Elmer - ELM

General Description

The Elm Monitor measures ozone (O3), nitrogen dioxide (NO2), total volatile organic compounds (VOC), particulate matter (PM10) noise, relative humidity (RH) and temperature (T). Some versions carry an optional nitric oxide (NO) or sulfur dioxide (SO2) sensor.

Principle of Operation

The device incorporates metal-oxide sensors to measure NO2, O3 and VOC. It also employs a light-scattering sensor to measure PM10. Noise is detected through a microphone, while a dielectric film is used to measure temperature and relative humidity.
Elm measures pollutant levels in real time, wirelessly transmitting the data to a cloud-based system for storage, analysis and processing.
