SEC Millennium Infrared LC Hydrocarbon Gas Detector
Description
The SEC Millennium LC hydrocarbon detectors are designed to be used as an upgrade in the same applications where catalytic bead sensors have been applied. The Millennium LC is a complete self contained optical hydrocarbon 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.
