Gas Leak Detector for gas pressure systems / Leakage assessment / Various attachments / Battery-operated handheld device / Touch colour display / Wireless headphones / Evaluation software / Calibration certificate

The gas leak detector for gas pressure systems is an effective solution for detecting and evaluating leaks in compressed air and other non-explosive gas pressure systems. The measured leaks can be recorded and analysed 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% in energy costs.

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

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