The Midas-M is a Fixed Extractive Single Point with 4-in-1 Multi Gas Detector to detect more than 30 gases - precisely, easily, quickly, that draws a sample locally or from a remote point to a sensor cartridge that is located inside the detector's chassis. A side range of toxic, flammable and oxygen gas sensor cartridges are available that enable detection of gases used or generated in the Semiconductor and other manufacturing industries.
- Over *33 gases available with 2 year warranty : 17 gases available at launch
- 4-in-1 multi smart sensor cartridge with on board * ‘e-calibration’ certificate
- Modular design for easy to use and service (front, pump, sensor cartridge, main and base)
- 3 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 need for frequent gas testing
- Isolated 0-21 mA analog 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 (2 year lifetime) sampling up to 100 feet
- Semiconductor processing
- Light industrial manufacturing
- University laboratories
- Aerospace
