electrochemical co sensor going off

Carbon Monoxide Alarm Detector FAQs |

If your carbon monoxide alarm went off, it detected a dangerous level of CO gas. Here are some reasons why a responder may not find CO during an investigation: Carbon monoxide gas dissipated in fresh air. If windows and doors open before a responder arrived, the same concentration of CO gas may no longer be present. Be safe first and vent dangerous carbon monoxide gas to the outside. The ...

False Alarms with Carbon Monoxide Detectors Firehouse ...

· I wouldn''t consider the CO alarms false. The alarms are going off as designed, it is the comsumers failure to understand what the specific alarm is telling them is where u run into your "false" CO calls. The alarm is designed to alarm, as has been said already, when it reaches a certain level and it needs to be reset, another alarm i see alot is older models when there battery goes bad the CO ...

How Does an Electrochemical Carbon Monoxide Sensor Work ...

Electrochemical sensors use a gel to detect CO. Electrochemical sensors are mainly used to detect Oxygen and toxic gas. They measure a chemical reaction within the sensor that creates an electrical output proportional to the CO level. Essentially, EC sensors are small fuel cells composed of noble metal electrodes in an electrolyte. AlphaSense is one of the most popular manufacturers of ...

1 Electrochemical sensors

1 Electrochemical sensors These sensors employ redox reactions to quantify the amount of an analyte. The current flowing through the system or the potential difference between the electrodes as a result of the oxidation and reduction reactions involving the analyte are used for its quantification in the sample. The electrochemical sensors do not suffer from the drawbacks of optical sensors ...

Gas information sheet 36: Carbon monoxide alarms for ...

Electrochemical sensor CO alarms, where a chemical reaction with CO gas creates an electrical current that sets off an alarm, are the most common type of CO alarm available. They are designed to trigger at certain CO concentrations and time periods. (Your CO alarm’s instruction sheet should provide triggering times and CO concentrations, which will vary.) The proximity of the alarm in ...
