What is a Gas Sniffer?

A gas sniffer s a handheld device used to detect the presence of gas and alert the user when the concentration exceeds a certain threshold. It is often part of a larger alarm system in commercial spaces to help people know it’s unsafe and they should leave. They can come in a variety of sizes and types and be designed to detect toxic, flammable or oxygen depletion gases.

Most gas detectors use a combination of two electrodes to detect the target gas. The sensor absorbs the gas and reacts with it, causing an electric current to flow between the electrodes. The gas sensor’s surface is coated with a material that allows only the targeted chemical to pass through, which ensures accuracy and specificity. The electrodes are connected by a wire that sends the signal to an alarming mechanism such as a vibrating screen or a loud sound.

Monitoring Carbon Monoxide: Low-Level Detectors for Enhanced Safety

Some gas sensors have a special feature to help the user identify the source of the detected gas. For example, some natural gas sensors are coated to emit a “rotten egg” scent that can help the user determine what kind of leak they may be dealing with. This could be something as simple as a pilot light going out or as complicated as a crack in the gas line.

Another common application for these tools is to inject the device with high-concentration carbon dioxide into a confined space to drive out or euthanize pests like bed bugs, ants, rodents and prairie dogs. The gas is driven in at a rapid rate and the pests will either flee or die from the noxious gas.
