Bacharach’s MGS-450 Gas Detector makes compliance with refrigeration safety
codes simple and easy, saving time and money on equipment and installation.
Using the MGS-400 App, users can intuitively use, commission and maintain their
gas detection system without the need for specialty training or tools. Pre-calibrated
sensor modules simplify maintenance, take minutes to exchange and do not require
the use of calibration gas.
The MGS-450 can trigger additional audio-visual alarms and act as a standalone gas
detection system, or integrate easily into a BMS / BAS or with Bacharach’s optional
MGS-408 Gas Detection Controller.
