Sensor Electronics Gas Detection / Detector

In 2021 (SEC) Sensor Electronics Corporation celebrated 30 years of being in the gas detection industry. Sensor Electronics is a worldwide leader in the development and production of innovative toxic gas detectors, infrared gas detectors and gas analyzers.

SEC MILLENIUM HAWK Hydrocarbon Gas Detector

The SEC Millenium Infrared Hydrocarbon Gas Detector 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 SEC Millenium Hydrocarbon infrared gas detector can operate as a stand-alone 4-20mA gas detector, or it can be coupled with a Sensor Electronics 3100 Transmitter Display.
