MGS-450 (IP66) Gas Detector, R407C 0-1,000ppm
The Bacharach MGS-450 refrigerant gas detector is designed for use in refrigeration applications and may be used as a standalone device, connected to the optional MGS-408 controller, or connected to a facility’s BMS / BAS. It enables compliance with refrigerant safety codes (ASHRAE 15 and EN 378) and features audible and visual alarms to alert personnel in the event of a refrigerant leak.

Bacharach’s MGS-400 Series Gas Detectors make compliance with refrigeration safety codes simple and easy, saving time and money on equipment and installation. Using the MGS-400 App (compatible with Android and iOS), 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.
MGS-400 Series Gas Detectors allow installers to daisy-chain power (24V DC) and Modbus communication cables across the system, and can be easily integrated into a BMS / BAS, or with Bacharach’s optional MGS-408 Gas Detection Controller.
The Bacharach MGS-400 series is offered in several formats with differing levels of functionality. The following is a brief overview of each.
