The Honeywell Midas gas detector is designed for gas detection in semiconductor processing and industrial manufacturing.  Detection of up to 35 gases is possible for toxic, ambient and flammable gases. Sensors are pre-calibrated, plug and play, allowing easy replacement without human error.  Using an extractive pump system, sampling is up to 100 feet (30 meters) using a 500 mL/min regulated flow rate to provide high accuracy.

The standard power supply and communications capabilities include three onboard relays, 0-22 mA analogue output and Modbus/TCP Ethernet digital outputs. Plus, the Midas Gas Detector includes the innovative Power over Ethernet (PoE) protocol — a single Ethernet connection for all power, control and communication requirements. Thanks to the Midas architecture, cost-effective integration with PLC and Fieldbus systems is greatly simplified.

To avoid errors in resetting instrument key parameters, access to configuration and calibration menus are password restricted.

For detection of NF3 and CxFy gases, two Pyrolyzer modules are available, standard or high-temperature. These can be paired and powered from any Midas detector.

  • Small footprint (150 x 65 x 153 mm)
  • Bright LEDs & intuitive icon-driven, large multicolour backlit LCD
  • Relays 2 alarm & 1 fault
  • Smart sensor cartridge with onboard ‘e-calibration’ certificate
  • Transport time 2 to 30 seconds maximum
  • Sample line tubing 0.125 in ID x 0.25 in OD
  • CE marked for the prevention of radio interference
  • Reflex sensor health check gives enhanced safety
  • TempraSureTM temperature compensation technology
  • Logged sensor history
  • Previously by MDA Scientific
