Midas-M

Fixed extractive, 4-in-1 multi-gas detector. 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 wide range of toxic, flammable and oxygen gas sensor cartridges is available that enable the detection of gases used or generated in the Semiconductor and other manufacturing industries.
