Gas leak detection Designed with Artificial Neural Network (ANN) intelligence and real-time broadband acoustic sound processing technology, the Gassonic Observer-i Ultrasonic Gas Leak Detector provides reliable ultrasonic gas leak detection with suppression of false alarms. The unit can fully analyze the sound spectrum above 12 kHz, providing a broader leak detection range and increased sensitivity to smaller gas leaks without interference from unwanted background noise.
