GS-CMD1 Carbon Monoxide Sensor (wall Mounted)

Description

The CMD series carbon monoxide detector uses an electrochemical sensor to monitor the carbon monoxide level and outputs a factory calibrated 4-20 mA or 0-10 Vdc (Please specify on any order), or optional Modbus signal. Optionally, the device may be  configured with an alarm relay. For the options, please also see recommended products section below.
