Carbon Monoxide Monitor and Controller

Short Description:

Model: GX-CO Series

Key words:
CO/Temperature/Humidity monitor
Avaliable Zero calibration
Replaceable CO sensor
Strong control setting and outpus
Real-time monitoring air carbon monoxide concentration, displaying CO measurements and 1-hour average. Temperature and relative humidity is optional. High quality Japanese sensor has five years liftime and is replaceable conveniently. Zero calibration and CO sensor replacement can be handled by end users. It provides one 0-10V / 4-20mA linear output, and two relay outputs, and optional RS485 with Modbus RTU. Buzzer alarm is available or disable, it’s widely used in BMS systems and ventilation control systems.
