MGS-250, Infrared Halocarbon Detector, Broadband

Part Number: 6401-0500

Gas Detection for CFC, HFC, HCFC and HFO refrigerants

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.

  • Long-life, proprietary infrared (NDIR) sensor provides 5-7 years of maintenance-free service while detecting the presence of a target gas down to 75 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
