Leak detectors

Carbon monoxide (CO) is a colourless, odourless and taste-free gas, but it is also poisonous. Its sources include the incomplete combustion of substances containing carbon, such as oil, gas and solid fuels. The hazardous nature of this gas means that it is necessary to regularly check CO emissions at combustion points of heating systems, and places often frequented by people and in the surrounding areas.
