MGS-250 Infrared Gas Detector

Infrared Gas Detector for Safety Compliance 

  • Long-life, proprietary infrared (NDIR) sensor
  • Detects CFCs, HFCs, HCFCs and new HFO refrigerants
  • Meets ASHRAE 15, EN 378, and CARB RMP requirements
  • 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

 

 Description
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*,
EN 14624* (* A1 Gases only), 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.
