Perkin Elmer ELM - Field Evaluation

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.
