insulating gas has high affinity to absorb this frequency of energy and appear as a dark cloud on the camera’s monitor (Fig 1). The image on the monitor provides a direct indication of how serious the leaks are by the size and darkness of the tracer-gas cloud. Equipment is portable and manageable by one service technician, he continued.Get price
