EQMS-200A Alarm TVOC Online Monitoring System

Overview Of EQMS-200A Alarm TVOC Online Monitoring System

EQMS-200A alarm TVOC online monitoring system adopts the PID photoion method for gas detection. The UV light produced by ion lamp irradiates on target gas, and the gas will be ionized after absorbing enough UV energy. The target gas concentration can be detected through the small current produced by gas ionization.

Feature Of EQMS-200A Alarm TVOC Online Monitoring System
