Bacharach MGS-410 Gas Detector

Bacharach MGS-410 Gas DetectorThe Bacharach MGS-410 Gas Detector is part of the MGS-400 series, Bacharach’s primary platform for refrigerant monitoring in industrial and commercial applications. Designed as a cost-effective solution for cold storage, chiller rooms, and machinery rooms, the MGS-410 combines robust performance with simple deployment.
The unit’s IP66-rated housing ensures resistance against dust, moisture, and harsh operating environments, while Modbus RTU communication enables seamless integration with building management and safety systems. As a standalone model, the MGS-410 does not include relay outputs but can be paired with Bacharach MGS controllers (MGS-402, MGS-408, MGS-401) for emergency ventilation activation, alarms, or shutdown systems.
The MGS-410 is compatible with Bacharach’s pre-calibrated, plug-and-play sensor technologies, including semiconductor, infrared, electrochemical, and catalytic bead sensors — covering refrigerants such as CO₂, ammonia, methane, R290, and halogenated gases. With integrated LED status indicators and built-in audio/visual alarms, it provides clear, on-the-spot gas monitoring that enhances safety and compliance with EN 378 and F-Gas requirements.
Ideal for operators seeking a durable, entry-level refrigerant gas detection solution, the MGS-410 balances affordability and functionality, backed by MSA Bacharach’s 110+ years of gas detection expertise and Frontline Safety’s trusted support.
