The Bacharach Leakator Jr Combustible Gas Leak Detector is suited for an array of commercial, residential and industrial applications.

The Leakator Jr is constructed with a flexible neck, long enough to identify leaks in areas that are difficult to access. The detector’s LED and audible sounds alert users to the presence of leaks while the automatic balance function identifies leaks in backgrounds where target gasses are present.

Equipped with a 5 year life sensor and UL 913 certification for hazardous environments, Bacharach’s Leakator Jr is the perfect choice for finding combustible gas leaks.
