Every fixture in your home’s plumbing system runs into one or more drains that lead to the sewer or septic system for the removal of waste and solids. When these drains are working properly, they only carry the waste and solids to the outside for treatment, but when they break or become clogged, sewage gasses can enter your home. A sewer gas monitor can identify this smelly, toxic gas.

The sensors in a sewer gas monitor detect the presence of these poisonous gases by using a variety of techniques. Some detectors use infrared sensors to pick up the odorous gasses, and others utilize electrochemical or catalytic sensors that react with these dangerous compounds. All of these types of sensors will produce a change in electrical resistance when they come into contact with the gases being monitored, which then triggers an alarm.

Sewer Gas Detection 101: How Sewer Gas Monitors Work”

In addition to picking up the rotten egg-like odor of sewer gas, the best sewer gas monitors will also be capable of monitoring other gases in confined spaces. These can include Hydrogen Sulfide (H2S), Carbon Monoxide (CO) and Methane (CH4). These are given off when waste decomposes and can be both toxic and flammable. It’s also important to monitor oxygen levels, as they can quickly become depleted in these environments.

To ensure that your sewer gas monitor will be able to detect all of these different gases, look for a multi-gas detector that is fitted with the ideal sensors. PK Safety carries both diffusion and pump-style monitors that will be able to provide you with the perfect solution for your needs.
