The Ultrasonic Leak and Corona Detector is a low-cost, portable system that receives air-borne ultrasonic signals, converts them to the audible range, amplifies them and displays the output visibly on a meter and audibly through a speaker or headset. The system is designed for locating gas leaks and electrical corona sources, all of which emit stro ...more

The MultiCAM System provides a simultaneous video image of an infrared spot and corona. This information assists the user in determining the location of the hot spot and/or corona and also, by a close examination, its possible cause. Since the video provides a moving image, it is possible to determine the seriousness of the hotspot (i.e. how the pa ...more
