7635Ultrasonic Leak Detector

Descriptions:

Ultrasonic leak detector utilizes ultrasonic sensor to check the air-tightness of pipeline. The operation is easy and accurate. The instrument can identify the gas leakage of various pressure or vacuum system.
The transmitter will generate 40kHz ultrasonic signal, and it is used in conjunction with the detector to detect the leaking location of the object. For example, the detector will detect signal leaking from the hole of the pipeline and as user moves the detector, the hole can be located correctly. The main application is the tightness test of any kinds, for example, doors, windows, plumbing, container, car windows, refrigerators … etc.

INSTRUCTION
To use on detecting the weak ultrasonic generating from the gas leaking, the leaking location can be located by moving the detector and listen to the voice generating from the detector. The transmitter will generating the ultrasonic signal, and if there is any leakage point, the signal will go through it and the detector can locate the point by listening to the signal.
Detector
  1. Connect the earphone with the earphone jack.
  2. Rotating the rotation switch to switch on the power. Power Indicator shall light up, if not, please change the battery. Rotating the rotation switch to adjust the sensitivity.
  3. Moving the sensor of the detector along the testing area slowly. If there is no leaking been detected, “LEAK” Indicator will not light up, and user will hear “DA – DA – DA” repeatedly from the earphone. As the detector approaching the leaking location, “LEAK” Indicator will start to light up, and the frequency and volume of “DA – DA – DA” voice will increase.
  4. Repair the leaking point and repeats test procedure (1) – (3) to make sure the leaking is sealed properly.
  5. Switch off the detector power. 
Transmitter
  1. Rotating the rotation switch to switch on the power. Power Indicator shall light up, if not, please change the battery.
  2. The transmitter will start to generate the ultrasonic signal, use the detector to detect the signal.
  3. Switch off the power after the test is done.
