According to Tracer, the PRO-Chek CG is twice as sensitive as competitive units, and features a three-position switch with a sensitivity slide that helps pinpoint the location of each leak fast.
Additional features include a variable-intensity auto alarm and flashing yellow LED to determine the size of the leak, and an auto-zero function that blocks out background gas levels, Tracer says. The detector comes complete with sensor, two D-cell batteries and a carrying case.
