SEC Millennium IR High Range Ammonia Gas Detector

The SEC IREvolution high range ammonia detector is designed to be used as an upgrade in the same applications where electrochemical sensors have been applied. The Millennium is a complete self contained optical ammonia gas detector. 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.
