High-precision gas leak detection


Instantly detect pressurized gas leaks with this high-precision, omni-direction acoustic detector utilizing Gassonic® ultrasonic technology. Works even when traditional methods of gas detection are unsuitable or dependent on ventilation. The Observer-i UGLD provides an industry-leading detection range (up to 28 m) reducing the number of detectors required.


Ideal for use in complex, outdoor pipeline systems - unaffected by wind, gas dilution, and direction of gas plume!



Artificial Neural Network (ANN) technology distinguishes real gas leak noise from background noise, suppressing false alarm sources

Does not require in-field training, fully operational after installation

Detects gas leaks from 2 BAR (29 psi) pressure for rapid detection of small gas leaks

Patented Senssonic™ self-test function ensures full fail-safe operation

Trouble-free maintenance and one-person check and calibration
