The Complete Gas Detection Solution for Safety Compliance

The MGS-400 Series is a complete leak detection solution, designed specifically for safety compliance in HVAC and refrigeration applications. Modern refrigeration systems are designed to be efficient and leak free, but improper installation, inadvertent damage or mechanical wear can result in potentially hazardous leaks. With their rapid response time, low-temperature performance (-40° C) and integrated audio & visual alarms, MGS-400 Series gas detectors make compliance with safety regulations simple and easy.

Refrigerant Safety Compliance Has Never Been More Intuitive

Low Temperature Performance

Effective Instrument Performance to -40° F / C

MGS-400 gas detectors feature refrigerant-specific sensors with temperature-compensated measurement to ensure effective performance across a wide temperature range.

Ensures that instruments maintain effective operation in refrigeration applications (machinery rooms, cold storage, walk-in freezers) where low temperatures are common:

  • Optimizes response time to the presence of the target gas
  • Mitigates false alarms (e.g. during defrost)
  • Minimizes cost of unnecessary engineer call-outs
  • Mitigates need for adjustment during commissioning

Simple Installation / Maintenance

Intuitive Installation / Maintenance Saves Time & Money

Instruments feature multiple cable glands, individual power / communications terminals and poke-yoke sensor modules.

MGS-400 gas detectors offer fast and intuitive installation, commissioning and maintenance:

  • Daisy-chain power & communications
  • Multiple cable entries (no crowding wiring in cable glands)
  • No special tools (multi-meters / potentiometers)
  • Fault type can be quickly identified via fault code in the field
  • Proactive maintenance enablement tools ("calibration due" indicator, sensor exposure counter)

MGS-400 Smartphone App

No more Specialty Tools / Training

Users can interface with MGS-400 gas detectors via the companion smartphone app.

Available for Android & iOS, the MGS-400 App communicates to gas detectors via Bluetooth® and allows users to quickly interface with the instrument:

  • View current gas measurement / acknowledge alarms
  • Configure instrument settings (alarm thresholds, Modbus settings, relay behavior)
  • Perform semi-automated calibration / bump test and generate field calibration certificate

BMS / BAS Integration

Communicate with Existing BMS / BAS Systems

All MGS-400 gas detectors feature the ability to interface with an MGS-408 Gas Detection Controller or other third-party BMS / BAS over Modbus (RS-485).

Communicate the full set of information from the instrument and enable at-a-glance visualization for all gas detectors in the system.
