Bacharach ’s Leakator 10 is a low maintenance combustible gas leak detection unit, small enough to be operated with just one hand, yet loaded with the kind of advanced features and technology professionals demand. Powered for up to 30 hours of continuous operation by alkaline C-cell batteries, the Leakator 10 comes complete with a flexible 20-inch long probe for hard-to-reach areas and a patented solid state sensor that will last for up to five years. The Leakator 10 allows you to pinpoint large and small leaks quickly, while checking a relatively large area in a short amount of time with absolutely no calibration required.
