MGS-250 Infrared Gas Detector
- Long-life, proprietary infrared (NDIR) sensor
- Detects CFCs, HFCs, HCFCs and new HFO refrigerants
- No cross interference to other gases, humidity or temperature
- Modbus RTU interface, analog output, BAS/BMS system connectivity
- Set all parameters and outputs without opening the unit
Bacharach’s MGS-250 Infrared Gas Detector is a cost-effective solution for compliance with refrigeration safety codes (ASHRAE 15, CSA-B52) and emissions reduction standards (F-Gas, CARB).
Long-life, proprietary infrared (NDIR) sensor provides 5-7 years of maintenance-free service while detecting the presence of a target gas down to 20 ppm Minimum Detection Level (MDL)
Sensor is not prone to false alarms caused by cross-interference from other gases or sudden changes in temperature or humidity
4-digit LED display shows real-time concentration readings and makes configuration and self-diagnostics intuitive
Configurable analog output (4-20mA, 0-5V, 0-10V, 1-5V or 2-10V) and Modbus communications for integration with Bacharach’s MGS-408 controller or third-party BMS / BAS control systems
User-configurable relay (alarm) may be used to activate external beacons / sounders, ventilation or other countermeasures
Integrated audible / visual alarms for refrigeration safety compliance – no additional hardware
Bacharach’s MGS-250 Infrared Refrigerant Gas Detector is the leader in performance and flexibility. It can be configured as either a broadband sensor used for gross leak detection, or as a gas-specific version that’s pre-calibrated and characterized for precision response to individual refrigerants. It meets ASHRAE 15, EN 378, and CARB RMP compliance requirements. The MGS-250 is the economical solution for detecting refrigerants without the limitations posed by solid-state sensor technologies.
Advanced infrared sensing technology makes the MGS-250 immune to cross sensitivities from combustible and toxic gases, as well as changes in temperature and humidity. The infrared sensor provides low-level leak detection and delivers up to 5 to 7 years of virtually maintenance-free operation. The MGS-250 has an alpha-numeric LED display, status indicator, on-board relay, and alarm to alert personnel when levels have exceeded the preset limit.
