The Honeywell Midas-M is a Fixed Extractive, Single Point with a 4-in-1 Multi-Gas Detector to detect more than 30 gases – precisely, efficiently, and quickly, that draws a sample locally or from a remote point to a sensor cartridge that is located inside the detector’s chassis. A wide range of toxic, flammable, and oxygen gas sensor cartridges are available to detect gases used or generated in the Semiconductor and other manufacturing industries.

Midas provides outputs of 0-22 mA analogue or Modbus/TCP Ethernet. Midas-M transmitters operate with Midas-M sensor cartridges for use as a local gas detector. Transmitters are powered by 24VDC or via Power over Ethernet (PoE).

Integral general relays for A1, A2 and fault are included and may be configured normally open or normally closed, latching or non-latching. Transmitters include Manual, Quick Start Guide, and (1) PG16 gland fitting for power in and relays out, 1/4″ O.D.x 1/8″ I.D. Sample Inlet tubing (10′) [3m], 1/4″ O.D x 3/16″ I.D. Exhaust tubing (10′) [3m], and a sample line tubing duct adapter (1283K1090). Generation 2 features a multi-coloured backlight to indicate status.

Features & Benefits:

  • Over 33 gases are available with a two-year warranty: 17 gases at launch
  • 4-in-1 multi-smart sensor cartridge with onboard ‘e-calibration’ certificate
  • Modular design for easy use and service (front, pump, sensor cartridge, main and base)
  • Three built-in relays (Form C) for Alarm 1, 2 and Fault
  • Power over Ethernet (PoE) communication
  • Keypad interface and remote web browser interface
  • Factory-calibrated sensors to reduce the need for frequent gas testing
  • Isolated 0-21 mA analogue output with fault and event reporting
  • Modbus/TCP Ethernet for easy connectivity to all control and alarm systems ports for control connectivity and service interaction
  • Robust extractive pump system (two-year lifetime) sampling up to 100 feet

Quick Specs:
