SenSmart 3400M Millenium IR CO2

The SenSmart 3900 3-wire gas detector is built with our reliable ‘ST-48’ smart transmitter, which provides the cutting-edge technology in toxic and combustible gas detection. It’s a universal, easy to use detector that supports Infrared sensors.

The microprocessor based intelligent SenSmart infrared gas detector is ideally suited for use in harsh environments and where conventional catalytic detectors is prohibitive. These infrared gas detectors perform reliably in the presence of silicone and other catalyst poisoning agents and operate in oxygen free environments or where high background gas levels are present.
