The Mini Gas Sniffer is a hand-held, hydrocarbon gas leak detector featuring a LED scale and beeper, which effectively pinpoints small leaks in piping. Inaccessible areas are reached with the 8-in. (200-mm) long flexible probe. The compact detector uses solid-state sensors having improved sensitivity, low power combustion and extended long life. Detectable gases include methane, butane, propane and LPG.
