A gas detector can sound an alarm to operators in the area where the leak is occurring, giving them the opportunity to leave. This type of device is important because there are many gases that can be harmful to organic life, such as humans or animals. Gas detectors can be used to detect combustible, flammable and toxic gases, and oxygen depletion.
For portable use, detectors have also been made which use the natural albedo of surrounding objects in place of the retroreflector. The presence of a chosen gas (or class of gases) is detected from its absorption of a suitable infrared wavelength in the beam. Rain, fog etc. in the measurement path can also reduce the strength of the received ...
The alarms will still alert you 100% of the time if a natural gas or carbon monoxide leak occurs, according to the manufacturer. For more smart consumer news coverage, please sign up for our free ...
A detector for propane is best placed down low near the floor, as propane is heavier than air. [3] A detector for natural gas (city gas) is best placed up high, near the ceiling. [3] Some detectors can detect both natural gas or propane, but this requires a compromise location. [4]
In order to analyse the concentration distribution present in the sensor tube, a pump pushes the column of air in the tube past a detection unit at a constant speed. The detector unit at the end of the sensor tube is equipped with gas sensors. Every increase in gas concentration results in a pronounced "leak peak". [6] [25] [26]
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.
