EQMS-200 VOCs Pollution Source Online Monitoring System
EQMS-200 VOCs Pollution Source Online Monitoring System adopts Photo Ionization Detection Method (PID) for gas detection. It uses ultraviolet light produced by ion lamp to irradiate the target gas and the target gas will be ionized after absorbing enough ultraviolet light. The concentration of the target gas can be detected by measuring the tiny current produced after gas ionization.
Feature
* IP65 protective design of high standard, can be installed indoors or outdoors
* Auto zeroing and auto calibration design, reduces work load of maintenance greatly
* Modular design, low maintenance cost
* Auto temperature and pressure compensation, accurately calculate gas concentration under normal pressure
* Equipped with visual alarm light for VOCs exceeding standard
* Battery module can be equipped for continuous monitoring when power out
