Portable Ultrasonic Leak Detector – DY26A Gas, Air, Water, Pressure & Vacuum Leak Tester for Flaw Detection, Inspection and Maintenance

Locate Pressure And Vacuum Leaks With Greater Confidence

Identify hard-to-find leaks without dismantling an entire system using the DY26A ultrasonic leak detector. This handheld tester detects ultrasonic emissions produced when gas or liquid moves through a small opening. It is designed for pressure and vacuum systems, making it useful for inspection, troubleshooting, and routine maintenance. Its portable format supports leak checks in workshops, HVAC environments, industrial facilities, and field locations.

Pinpoint Leaks With Ultrasonic Sensing

The detector responds to ultrasonic sound around 40kHz, a frequency commonly generated by pressurized leaks. Move the probe slowly around seals, joints, pipes, valves, and other suspected areas to narrow down the source. As the probe approaches a leak, the ticking tone increases in frequency and the leak indicator illuminates. This directional response helps you focus on the affected location before beginning repairs.

Adjust Sensitivity For Different Environments

An adjustable sensitivity control helps adapt the detector to the strength of the ultrasonic signal. Start with a higher setting when the leak is difficult to detect, then reduce sensitivity as the probe moves closer to the source. Lowering the sensitivity can also help limit interference in noisy working environments. This controlled approach makes it easier to distinguish the suspected leak from surrounding ultrasonic activity.

Carry It Between Inspection Areas

The compact handheld design makes the DY26A convenient for maintenance routes and field inspections. Its package measures 26 x 19 x 9 cm and weighs approximately 0.469 kg for manageable transport and storage. The device uses a 9V 6F22 battery or equivalent, removing the need for a nearby outlet during testing. CE certification provides added assurance for users seeking a compliant inspection tool.

Make Leak Inspection More Focused

The DY26A provides a practical way to locate ultrasonic emissions from pressurized gas and liquid leaks. Adjustable sensitivity, audible feedback, and a visible leak indicator help guide the inspection toward the suspected source. Its portable construction works well for HVAC maintenance, industrial equipment checks, and general pressure or vacuum system testing. Keep it with your diagnostic tools when you need a focused method for locating difficult leaks.
