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. This applies to all CO safety alarms that meet ...
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. This type of device is important because there are many gases that can be harmful to organic life, such as ...
A smoke detector is a device that senses smoke, typically as an indicator of fire. Smoke detectors/Alarms are usually housed in plastic enclosures, typically shaped like a disk about 150 millimetres (6 in) in diameter and 25 millimetres (1 in) thick, but shape and size vary. Smoke can be detected either optically (photoelectric) or by physical ...
A reliable smoke detector that also detects carbon monoxide just might save your life. Fortunately, the First Alert smoke and carbon monoxide detector is on sale for $22, or $41 off its list price!
Since the detection mechanism involves the oxidation or reduction of the gas, electrochemical sensors are usually only suitable for electrochemically active gases, though it is possible to detect electrochemically inert gases indirectly if the gas interacts with another species in the sensor that then produces a response. [3] Sensors for carbon ...
In buildings, carbon monoxide detectors are usually installed around heaters and other equipment. If a relatively high level of carbon monoxide is detected, the device sounds an alarm, giving people the chance to evacuate and ventilate the building. [94] [96] Unlike smoke detectors, carbon monoxide detectors do not need to be placed near ...
