2. Gas detector - Wikipedia

   en.wikipedia.org/wiki/Gas_detector

   A gas detector is a device that detects the presence of gases in an area, often as part of a safety system. A gas detector can sound an alarm to operators in the area where the leak is occurring, giving them the opportunity to leave.

   Smoke detectors aren't the only safety device that should be installed in every home. Carbon monoxide detectors are just as important for ensuring health and wellness. Most homes use at least one ...

4. Carbon monoxide detector - Wikipedia

   en.wikipedia.org/wiki/Carbon_monoxide_detector

   A Kidde plug-in carbon monoxide detector. A carbon monoxide detector or CO detector is a device that detects the presence of the carbon monoxide (CO) gas to prevent carbon monoxide poisoning. In the late 1990s, Underwriters Laboratories changed the definition of a single station CO detector with a sound device to carbon monoxide (CO) alarm.

5. Electrochemical gas sensor - Wikipedia

   en.wikipedia.org/wiki/Electrochemical_gas_sensor

   For some gases, such as ethylene oxide, cross-sensitivity can be a problem because ethylene oxide requires a very active working electrode catalyst and high operating potential for its oxidation. Therefore, gases that are more easily oxidized, such as alcohols and carbon monoxide will also give a response. Cross-sensitivity problems can be ...

6. Chemiresistor - Wikipedia

   en.wikipedia.org/wiki/Chemiresistor

   Metal oxide chemiresistor sensors were first commercialized in 1970 [12] in a carbon monoxide detector that used powdered SnO 2. However, there are many other metal oxides that have chemiresistive properties. Metal oxide sensors are primarily gas sensors, and they can sense both oxidizing and reducing gases. [2]

7. Workplace exposure monitoring - Wikipedia

   en.wikipedia.org/wiki/Workplace_exposure_monitoring

   Direct-read instruments give immediate data, and include colorimetric indicators such as gas detector tubes, and electronic devices such as gas monitors and aerosol particle counters. In addition, samples may be collected and sent to a laboratory for slower but often more thorough analysis.
