Elitech - Temtop PMD 351

General Description

The Elitech Temtop PMD 351 sensor is a portable, battery-operated handheld mass monitor that provides real-time mass concentration measurements of PM1.0, PM2.5, PM4.0, PM10 and Total Suspended Particles (TSP); the detected mass concentration information can be viewed on the display screen. The sensor comes with the filter to perform a zero calibration. Zero calibration and flow calibration are recommended before deploying the sensors.

Principle of Operation

The measurement principle of the Elitech Temtop PMD 351 sensor is based on laser scattering to convert particle number to mass concentrations through its proprietary algorithm. The sensor comes factory calibrated with a certificate.
