Carbon Monoxide Sensor Cross-Sensitivities Alcohols, VOCs ...

Carbon Monoxide Sensor Cross-Sensitivities Alcohols, VOCs & Hydrogen Technical Bulletin Cross-sensitivity to gases other than the target gas of interest is a common sensor characteristic, especially among electrochemical sensors. Cross-sensitivities are limited as much as possible by MSA sensor design and filters; however, some key interactions still occur. CO sensors do have some inherent ...

12/24VDC Carbon Monoxide Detector with SafeTest

The 260-CO carbon monoxide (CO) detector is an accurate and reliable means of alerting building occupants of potentially danger-ous levels of CO in the protected area. The internal electro-chemi- cal sensor communicates with a sophisticated on-board micropro-cessor that accurately tracks CO levels over time. This commercial-grade detection technology results in quick response, reliable sensing ...

How do carbon monoxide detectors work? - Explain that Stuff

· When carbon monoxide is present, the electrolyte conducts electricity more readily, making a current flow in a detector circuit, and triggering an alarm. Electrolytic detectors are usually the most sensitive and accurate—and therefore also the most expensive. They also need powering from an electricity outlet, instead of batteries, which means they may not be suitable if you don't have an ...
