Description

The MGD-100 is an affordable and scalable gas detection system used to provide real-time monitoring of refrigerant and combustible gases, ammonia and carbon dioxide. The unit alarms when pre-set thresholds are exceeded. Alarms are monitored by a centralized controller, which can alert personnel of potential hazardous conditions via an onboard buzzer and LED alarm indicators.

The unit can be configured from single-sensor, one-alarm level system to larger scale systems consisting of 6 sensors with 2 alarm levels. The instruments are connected to and powered by the MGD controller. A variety of housing options are available including IP41 and IP66 rated enclosures, which enable direct placement of the MGD-100 in a variety of environments. For special applications, the sensor can be remotely mounted from the instrument.
