SEC Millennium Infrared Carbon Dioxide Gas Detector

CO2 Infrared Transmitter

The SEC infrared carbon dioxide detector is a single source dual wavelength instrument. The sensing and reference elements are self-compensating for optical integrity and other signal inhibitors. The industry standard 4-20 mA analog output provides remote alarm, fault and calibration signals.
