Ammonia (NH3) Fixed Gas Detection System | Industrial Refrigeration & Facility Gas Monitoring System
Couldn't load pickup availability
The Ammonia (NH₃) Fixed Gas Detection System with Remote Sensor (MSC2) is an industrial-grade ammonia gas detector designed for continuous NH3 monitoring in high-risk environments including refrigeration systems, laboratories, agriculture and industrial facilities.
Ammonia is a toxic and corrosive gas that can quickly reach dangerous concentrations, putting personnel, equipment, and compliance at risk. This fixed ammonia gas detection system provides real-time monitoring, early leak detection, and automated alarm response to help prevent exposure incidents and costly downtime.
Built on the flexible MSC2 multi-gas safety platform, this system uses a remote ammonia gas sensor to detect leaks at the source in order to trigger alarms, activate ventilation systems and create rapid response.
