TPI 721 Combustible Gas Detector is rated 5.0 out of 5 by 1.
Rated 5 out of 5 by from TPI 721 Gas Leak Detector Great bit of kit, not cheap but worth every penny. Allowed me to identify a gas leak in my boiler that 4 Engineers said wasn't there and hence get fixed. It was only a very small leak but this detector was able to pick it up.
