Ultrasonic Camera for Gas Leak Detection

Pinpoint leaks of any gas up to 50m away

Ultra Pro is a hand-held ultrasonic camera that literally sees gas leaks from the specific sound they emit. Using its 128 integrated microphones, it pinpoints leaks of all gases including methane, air, hydrogen, steam, vacuum... The leak location is indicated in real-time on an integrated screen. Pictures and videos can be recorded and integrated into digital reports with Distran Audalytics.

About Distran AG

Distran develops and sells the world first ultrasonic cameras able to pinpoint leaks of any gas, air and vacuum. Leaks can be spotted from a safe distance, up to 50m away. Used in more than 18 countries, the device is particularly suited for the maintenance of industrial plants (e.g power plants, refineries, air separation, semi-conductor industry) or for improving energy efficiency (compressed air, atmospheric gases). Headquartered in Zurich, Switzerland, the company employs 18 people, incl. PhD, engineers and senior field experts.


Distran AG is the winner of the VBSF Safety award 2020 thanks to their innovative technology for detecting gas leaks. The Distran company in Zurich received the Safety Prize 2020 from the Swiss Association of Fire Protection and Security Experts (VBSF).
