Combustible Gas Detectors
General Tools & Instruments (General Tools)
A leak of natural gas (methane), propane or butane can cause an explosion in a basement with a sloppily installed unit as easily as it can in a coal mine. General sells these life-saving combustible gas detectors in various shapes and sizes, including pens and wands with a probe. Two models, the NGD268 & PNGD170 Combustible Gas Detectors even work from -40 to 158F, the extreme environment typical of mines and tunnel construction.
