· The CO sensors use the improved electrochemical sensor. It also includes a backup battery which allows it to provide continuous monitoring even when the power goes off. Additionally, the alarm features indicator lights on its face which goes on when the sensors sense the presence of smoke or carbon monoxide. I wouldn’t forget to mention that ...
The electrochemical sensor gives a rapid response to the target gas. For example, the SPEC CO sensor typically reaches 90% of the full response to a step-change in concentration in <15. SPEC Sensor Operation Overview May 2016 SPEC Sensors, LLC SPEC Sensor Operation Overview 051016 seconds. However, for accurate calibration, it is recommended that you expose the sensor to …
battery powered devices, such as carbon monoxide (CO) gas and environmental monitors. Because of the nature of these sensors, they must be continuously biased to maintain proper operation. Power cycling is generally not suitable because of the long recovery time, re-zeroing requirements, or even possible sensor damage that power cycling causes. The ideal configuration is to leave the sensor ...
