TPI 725L Pocket Gas Sniffer w/Flexi-neck

TPI 725L Pocket Gas Sniffer w/Flexi-neck provides fast and reliable detection of combustible gases in domestic and light commercial settings. It is designed to help engineers and maintenance teams locate leaks quickly and safely. With a compact body and simple controls, it supports efficient testing in tight spaces.

Built with a flexible neck, TPI 725L allows precise positioning around pipework, valves and fittings. This makes it ideal for tracing leaks along natural gas lines, LPG systems and storage tanks. The unit responds instantly when gas is present, helping reduce inspection time on site.

Leak Detection Performance

TPI 725L detects methane with a sensitivity greater than 40 ppm. In addition, it responds to butane, propane, petrol, diesel and kerosene vapours. When gas vapour is detected, the tick rate increases and the green LED flashes faster. If levels rise above 1000 ppm methane, the high LED illuminates to give a clear visual warning.

Simple Operation and Clear Alerts

Using TPI 725L is straightforward. In clean air, press the ON/OFF key and the unit auto zeroes during start-up. Once ready, a steady slow tick and green LED flash confirm normal operation. As you move towards a leak, the audible tick speeds up to guide you to the source.

To pinpoint the exact leak location, press and release the ON/OFF key to nullify the tick rate. This function removes background gas readings and allows you to focus on the highest concentration point. Press and hold the key to power the unit off after use.

Key Features
  • 40 ppm sensitivity to Methane
  • 185mm flexible neck for accessibility
  • Detects a wide range of combustible gases
  • Allows setting of ‘new zero’ to identify leaks
  • Resets levels for fresh detection on restart
  • Ideal for various applications, from tracing lines to testing tanks
Technical Specifications
  • Sensitivity: 40 ppm to Methane
  • Neck Length: 185mm flexible
  • Detectable Gases: Methane, Butane, Propane, Gasoline, Diesel, Kerosene
