SenSmart 7400M Millenium IR CO2 Gas Detector

The SenSmart 7400 wireless gas detector, with ultra-low power design and easy to use features, provides the most advanced, economical and reliable true wireless combustible gas detection solution. The SenSmart 7400 is compatible with the new low-power infrared sensor for hydrocarbon combustibles.

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.
