The Honeywell Midas®-M is a fixed extractive, single-point, 4-in-1 multi-gas detector designed for continuous monitoring of toxic, flammable, and oxygen gases. It draws a gas sample either from the local environment or from a remote sampling point and delivers it to a smart sensor cartridge installed inside the detector. Honeywell offers sensor cartridges for more than 30 gases, making the Midas-M suitable for semiconductor manufacturing and other industrial manufacturing applications.

Get A QuoteThe Midas-M uses a plug-and-play smart sensor cartridge with an onboard e-calibration certificate, helping simplify installation, replacement, and commissioning. Its modular construction allows the front, pump, sensor cartridge, main electronics, and base to be serviced separately. A built-in pump can sample from locations up to 100 ft (30 m) away, while optional Line Integrity Testing can help identify leaks in the sampling tubing.
For system integration, the detector provides 0–21 mA analog output, Modbus/TCP Ethernet, three Form C relays, and Power over Ethernet (PoE). A backlit LCD, keypad, event logging, remote web-browser interface, and Reflex® sensor health monitoring provide convenient operation and maintenance.
