Safety first.

We are proud to carry the full line of MSA and Bacharach commercial fixed gas and flame detection products.

MSA and Bacharach gas detectors are used in parking garages, mechanical equipment rooms, and hazardous storage rooms throughout the world.

MSA Bacharach’s MGS-400 and MGS-500 and MGS-250 Series Gas Detectors make compliance with mechanical equipment room and refrigeration safety codes simple and easy, saving time and money on equipment and installation. Using the MGS 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-400 and 500 sensors can trigger additional audio-visual alarms and act as a standalone gas detection system, or integrate easily into a BMS / BAS or with MGS-402 or MGS-408 Gas Detection Controllers.

MSA Bacharach’s MGS-450 Gas Detector and Multi-Zone Refrigerant Gas Monitor makes compliance with refrigeration safety codes (ASHRAE 15, EN 378, CSA-B52) simple and effective, saving time and money on equipment and installation.

MSA Bacharach gas detection systems are ready for your gas detection project, from the simplest system to the most complex.


The MSA Bacharach MGS-400 App allows users to configure, maintain and interface with compatible MGS-400 gas detectors. Once a Bluetooth connection has been established, the app replaces the need for specialty training / tools and makes compliance with safety standards (ASHRAE 15, EN 378) easy and effective.
