Up to three independent Secondary Monitoring Units with its own Sensor, LCD readout and alarm can be attached to the Primary Unit. The CO2 Sensor is an external unit for monitoring systems that can be mounted remotely, typically near floor level where gas ruminates, while the monitor and readout is mounted at convenient eye level. The Sensor may be mounted in a different room, such as a walk-in cooler, with the monitor and alarms outside.
