Overview
Enviro Test Construct digital gas detector with remote monitoring and high accuracy sensors digital display gas detector integrates audible and visual alarms, providing real-time monitoring of gas concentrations on-site. It features infrared remote control for parameter setting without opening the cover.
The converts the gas concentration signal from the air into an electrical signal for remote transmission. The device uses a three-wire 4-20mA output, allowing direct upload to DCS or PLC systems or using it independently. It also includes two sets of passive switch outputs for controlling other devices on-site, offering advantages such as long transmission distances and strong interference resistance.
