TPI 725A Pocket Combustible Gas Leak Detector

TPI 725A Pocket Combustible Gas Leak Detector

The TPI 725A Pocket Combustible Gas Leak Detector provides a quick way to check equipment, pipework and enclosed areas for combustible gas. Its compact body fits into a shirt pocket, making it easy to keep close during routine inspections. Visual LED indicators and an audible alarm give clear feedback when the instrument detects gas.

Real-time response helps the user follow a leak along gas lines, joints, fittings and connections. As the detected concentration rises, the staged LED display shows the relative leak level. This feedback can reduce the time spent searching for the affected area, although the instrument does not determine the exact source by itself.

Suitable for professional maintenance and domestic checks, the TPI 725A Pocket Combustible Gas Leak Detector can test for methane, natural gas, propane and several other combustible gases. It auto-zeros and responds instantly, so checks can begin without complex controls. Two AAA batteries power the unit for up to three hours of continuous use.

Key Benefits

• Fits into a shirt pocket for convenient carrying between inspection points.
• Responds instantly to support quick checks and faster fault finding.
• Uses visual LED levels to show when the detected gas concentration rises.
• Sounds an audible alarm, so the user does not need to watch the display continuously.
• Helps trace leaks along natural gas lines, fittings and connections.
• Auto-zero operation keeps set-up simple during routine checks.
• Checks several combustible gases with one compact instrument.
• Supports inspections in confined spaces where gas may have accumulated.
• Uses widely available AAA alkaline batteries for straightforward power replacement.

Common Applications

TPI 725A Pocket Combustible Gas Leak Detector is suitable for a range of testing, maintenance and inspection tasks, including:

• Tracing leaks along natural gas lines and fittings
• Checking gas appliances for combustible gas leaks
• Inspecting propane tanks, fittings, lines and heaters
• Checking gas generators for fuel leaks
• Testing fuel tanks and fuel storage areas
• Checking connections and pipe joints
• Testing confined spaces for gas accumulation
• Carrying out routine professional maintenance checks
• Completing domestic combustible gas checks

Why Choose This Model?

This pocket-sized model suits users who need preset LED leak levels and an audible warning for straightforward combustible gas checks. The HXG-2 and 720b provide greater sensitivity and an adjustable tick rate for tracing a source, while the 735 and 775 also test carbon monoxide in ambient air.

Specification Notes

• The supplied information gives both 40 ppm methane and greater than 1,000 ppm methane as sensitivity figures.
• The supplied technical table states a maximum displayed concentration of up to 5,000 ppm, while Leak Level 4 is shown as greater than 5,000 ppm methane.
• The staged LED readings indicate relative leak levels; the instrument can detect a leak but does not determine its exact source.
