The working principle:
If a container or pipe is filled with gas, when its internal pressure is stronger than the external pressure, due to the large internal and external pressure difference, once the container has a leak, gas will be flushed out of the leak hole. When the size of the leak hole is small and the Reynolds number is high, the turbulence will be formed when the gas blows out. The turbulence will produce a certain frequency of sound waves near the leak hole. The frequency of the acoustic wave vibration is related to the size of the leak hole. Audible sounds can be heard. When the leak is small and the sound wave frequency is high, the human ear cannot hear it, but they can spread in the air and are called no-load ultrasonic waves. Ultrasound is a high-frequency short-wave signal, and its intensity rapidly decays as the propagation distance increases. Ultrasonic waves have directionality. With this feature, the correct leak location can be determined.

Connect the earphone to the earphone jack of the leak detector, put on the earphone, operate the detector, and judge the location of the leak according to the indicator light and the frequency sound emitted by the earphone
Way of working:
The EM282-R can work with dynamic and main dynamics. When real-time inspection of the gas pipeline, it can be used alone, use it to capture the tiny ultrasonic signals generated when the gas leak, you can determine the correct location of the leak. This way of working is called dynamic.
When the EM282-R and EM282-T are used together, non-real-time inspection can be performed on the object to be inspected. That is, an ultrasonic signal of a certain frequency is emitted by the EM282-T. Once a leak occurs, the ultrasonic leaks from the leak hole and the leak is captured by the EM282-R. The ultrasonic information can be used to determine the correct leak location. This way of working is called main dynamics. Compared with the dynamic working mode, the main dynamic working mode is not suitable for real-time inspection, but has higher reliability.
Can generate 40KHz ultrasonic signal
When used with the EM282-R detector, it can perform non-real-time inspection of the detected object. The EM282-R can capture the signal emitted by the EM282-T leaking from the leak to determine the correct leak location.

Ultrasonic Leak Detector with Located the Leak Location Quickly: The leak detector adopts advanced ultrasonic sensor technology, Use sound waves with frequencies generated near the leak to determine the correct location of the leak, can quickly, accurately and intuitively find out all types of pressure or vacuum system gas.
Air Leak Detector with Multi-scene leak detection: Liquid leakage faults can detect the degree of sealing of enclosed parts such as cabins, car cockpits, refrigerators, and containers. Place the transmitter in the vehicle and close the doors and windows.Trace the detector around outside of the screen, windows and door seals to locate the leak
Ultrasonic Leak Detector with Excellent Quality：The ultrasonic leak detector has the advantages of small size, light weight, accurate and reliable, convenient operation, practicality, etc. It is a practical portable detection instrument.
Snoop Leak Detector with Two Measurement Methods: For real-time detection of gas pipelines, EM282-R can be used alone to capture the tiny ultrasonic signals generated when gas leaks to detect gas leaks; And non-real-time detection is that EM282-R capture the ultrasonic signal from EM282-T. Once a leak occurs, ultrasonic waves will leak out through the leak to determine the correct location of the leak.
Noise Detector with Sensitivity Can be Adjusted: the ultrasonic frequency response is within 40kHz +/-2kHz, which can be adjusted according to the detection environment to improve the accuracy of the measurement. At the same time, it is equipped with headphones and LED indicators, even the smallest sound can quickly capture the location of the leak
