Professional Gas Detectors for Combustible Gases

Buy gas detectors to detect leakages of flammable gas such as piped Natural Gas or bottled gas (LPG gas). These gas alarms will notify you if for example a cooker hob has been left turned on without a flame or if the gas oven flame has blown out. We also sell gas detectors for boats to detect dangerous concentration of propane and butane in the bilge of the boat, as well as professional gas leak testing equipment from Anton Group.

Gas Detectors

Our range of flammable gas detectors is designed to protect you from leaking flammable or explosive gases such as propane, butane, methane, as present in LPG or natural gas. By detecting the presence of explosive gases before a critical concentration is reached, the cause of the leak can be fixed in time or the premises can safely be evacuated.
