TPI 721 Hand Held Combustible Gas Leak Detector

The TPI 721 offers 10ppm sensitivity to detect combustible gasses. Easily operated with one hand, leaks are pinpointed using the audio and visual indicators. An adjustable “tic” rate helps eliminate background gas concentration in contaminated environments.

The 721 Combustible Gas Detector seeks out combustible gas leaks with a graph sensitivity levels. Notifies the user of leaks as low as 10 parts per million of methane.

Applications:

Detect combustible gasses including natural gas methane, propane (LPG), gasoline, diesel, and kerosene
Trace natural gas lines and fittings for leaks
Check gas generation for leaks

Very nice product. Easy and comfortable to use. Love the display and the info it provides. One really nice thing is that it can't accidentally be turned on when stored in truck like some other brands with rotary on switch.
