Leak detector Unit UT336B — long battery life, 6 sensitivity levels, audible and visual signals, auto power-on

The Unit UT336B handheld leak detector is designed to locate gas and air leaks quickly and reliably. It offers six adjustable sensitivity levels to detect a wide range of leak sizes, and provides both audible and visual signals to indicate the presence and intensity of a leak. Automatic power-on reduces setup time, while the long battery life supports extended field inspections and routine maintenance tasks.

Advantages

The detector’s six sensitivity levels enable gradual detection from small to large leaks, improving accuracy during search and pinpointing. Audible beeps and a visual signal bar give immediate, dual-mode feedback that helps users assess leak severity without ambiguity. Automatic power-on speeds up inspections by activating the device when needed, and the extended battery performance minimizes downtime and the need for frequent battery replacement. The handheld form factor and intuitive controls simplify operation in confined or hard-to-reach areas.

Suitable for

• HVAC system maintenance and leak location
• Gas line inspections and safety checks
• Industrial troubleshooting of pneumatic systems
• Preventive maintenance in commercial and residential buildings
• Field technicians performing rapid leak surveys

Key specifications

• Six adjustable sensitivity levels for variable leak detection
• Audible signal (beeper) to indicate leak presence and intensity
• Visual signal bar to display leak strength
• Automatic power-on to reduce setup time
• Handheld ergonomic design for access to confined spaces
• Long battery life suited for extended inspections

How to use

Switch on the unit to let the automatic power-on or manual activation initialize the detector. Select an appropriate sensitivity level based on the expected leak size — start with a lower sensitivity for larger leaks and increase sensitivity to detect smaller leaks. Move the probe slowly along joints, fittings, valves and pipe surfaces while observing the visual signal bar and listening for audible beeps. Pause briefly where the signals intensify to confirm and localize the source. After inspection, power the unit off and store it in a dry, safe place.

Usage recommendations

For best results, perform leak detection in a controlled environment when possible: reduce background airflow, isolate system sections, and clean surfaces before scanning. Calibrate sensitivity according to ambient conditions, and allow the detector to stabilize after powering on. Replace batteries promptly when signal strength or response becomes inconsistent.
