MSA Observer® i Ultrasonic Gas Leak Detector

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. Features Artificial Neural  Network (ANN) technology that distinguishes between real gas leaks and false  alarm sources without requiring any in-field training. 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.
