Ultrasonic Leak Detector Transmitter Pressure Vaccum Locator em2268

all-sun EM2268 Ultrasonic Leak Detector&Transmitter 36KHz-44KHz Pressure Vaccum System Locator Air Water Dust Leak Detector

 This instrument uses ultrasonic sensing technology with small size and light  Weight.
> It is a reliable, easy to use, practical and portable tool.
> By using this instrument, you can quickly and accurately locate leaks in any pressure and vacuum system. 
> It is very suitable for detecting cracks of pipes, valves, etc. 
> And it is very suitable for tightness check to cabin, plane, vehicle cabinet, refrigerator, freezing plant, oil tank and other sealed compartments.
> In addition, it can be used to detect electrical discharge in switches, transformers, insulators, circuit breakers, relay, bus bars and etc to prevent accidents.

 Working Principle >>>
Turbulence is created by gas or air forced through a small orifice generates ultrasonic  sound. Ultrasonic sound occurs when the atmosphere leaks into a vacuum vessel or when a pressure vessel leaks to the outside atmosphere. Ultrasonic sound's frequency is related to the size of the orifice which ultrasonic sound passes through, but usually the frequency is about 40Hz. Ultrasonic sound is very directional, this directionality is used to pinpoint the origin of the ultrasonic sound, the leak point.
