SEC Millennium Infrared LC Hydrocarbon Gas Detector

Category: Tags: , , ,

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.
