The Bacharach Leakator® Jr. is a compact, handheld combustible gas leak detector used to pinpoint combustible gas leaks in commercial, residential, and industrial applications, including surveying gas pipelines, and inspecting valves, regulators, and meters on gas equipment.

Measuring only 6 inches in length with a 12-inch flexible probe, Bacharach's Leakator® Jr. is a low maintenance instrument that requires absolutely no calibration. When combustible gases are sensed both audible and visual indication will be given.

    The Leakator® Jr. will detect nearly all combustible gases including:

  • Acetone, acetylene, benzene, butane, ethanol, ethylene oxide, gasoline, hexane, hydrogen, industrial solvents, iso-butane, methane, methanol, paint thinners, propane, natural gas, and naptha.

The Bacharach Leakator® Jr. ships complete with gas sensor, flexible probe, batteries and manual.
