PCE Leak detector PCE-LDC 20

The leak detector for pressurised gas systems is an effective solution for detecting and evaluating leaks in compressed air and other non-explosive pressurised gas systems.
The measured leaks can be recorded and evaluated within the software, the escape of compressed air causes high electricity costs as compressors run more than they should. Detecting leaks at an early stage can save up to 30% on energy costs.

Small leaks in pressurised systems generate ultrasonic sounds that are inaudible to humans. By using an ultrasonic microphone, the leak detector can measure frequencies that go beyond the limits of human hearing. The leak detector’s high-quality measurement electronics convert the recorded ultrasonic tones into sounds audible to the user, which the leak detector transmits via Bluetooth or via the 3.5 mm jack plug.

This leak detector allows the user to document even the smallest leaks, the leak detector can photograph the leak and record a voice memo. The leak detector also provides information on how much compressed air or gas is escaping through the leak. The leak detector therefore enables precise and efficient leak detection and assessment.
