TPI 725L Gas Leak Detector

This gas sniffer will also detect other combustible gases including:  Butane, Propane, Gasoline, Diesel and Kerosene.

The tick rate can be nullified to eliminate background gas concentration and pinpoint the leak source.

It's a robust, easy to use device.

• 40ppm methane sensitivity and bearing defects
• Trace natural gas lines and fittings for leaks frame to failure
• Check gas equipment for leaks
• Test propane tanks, fittings, lines, and heaters for leaks
• Check propane tanks, fitting lines, and heaters for leaks
• Test confined spaces for gas build-up

How to use the TPI 725L gas sniffer

In a clean air environment, press the ON/OFF key to turn the device on. Both LED’s will flash as the unit initializes and auto zeroes. When the green LED above the ON/OFF switch flashes and a tick is heard the 725L is ready for use.

Approach suspected leak areas with the sensor. When a leak above 40ppm is detected the 725L tick and green LED flash rate will increase.

When the tick rate increases press and release the ON/OFF key to nullify the tick and continue to approach the suspected leak area with the sensor. Continue to nullify the tick when the rate increases until the location of the leak is found.

If the tick slows or stops on its own the concentration level has decreased. Move back in the opposite direction to find the leak again.

If the leak reaches 1000ppm or above the high LED will illuminate (see below).

To turn the 725L off, press and hold the ON/OFF key down until the unit powers off.
