Tracer gas leak detectors use sensors to identify dangerous levels of combustible or toxic gases, usually sounding an alarm and warning people not to enter the area. They can be found in places like kitchens, boiler rooms, and garages to detect any gas leaks from leaking stoves, ovens, water heaters, or from automobiles in the area. Some have app-based alerts that can send information to smartphones, as well as smart home integration to help users monitor their appliances from anywhere.

Choosing the Right Tracer Gas Leak Detector: A Buyer’s Guide

Various types of gas detectors exist, each with unique detection methods. For example, a catalytic bead sensor uses a platinum-treated wire coil that oxidizes when exposed to combustible gas and triggers an alarm. These are typically found in homes and can detect a wide range of gases, including carbon monoxide.

Other devices feature a solid state sensor that uses a material (usually tin oxide or aluminum oxide) that can be formed into a bead-type sensor. The sensor can then be heated to raise its temperature, which can cause the sensor to change conductivity when it comes in contact with combustible gases or vapors. When the sensor cools down again, it returns to its original state and can be detected by a pair of biased electrodes within the device.

Stationary devices, typically installed on a wall or high up in a ceiling, can detect combustible and toxic gases as well as smoke from cigarette smoking or cooking. They can also include features such as a hard of hearing alarm that sounds a strobe light or vibration when triggered. These can be useful for workers who cannot hear an alarm, or for hard of hearing individuals whose sense of smell has declined over time.
