The Gas Leak Detector is used to locate leaks on compressed air lines. Furthermore, the Gas Leak Detector can also be used on coolant lines or gas lines for leak detection. The Gas Leak Detector is equipped with an ultrasonic sensor that can precisely detect leaks in air lines. The ultrasound sensor from the Gas Leak Detector works at a frequency of 40 kHz. This means that the Gas Leak Detector is calibrated to the medium frequency that leaks on pressure lines emit. This is in the range between 20 … 80 kHz. In order to perform better leak detection, a high-pass filter in the leak detector ensures that all noises are filtered at a frequency <40 kHz. An integrated amplifier element in the leak detector ensures that the high-frequency tones.
In addition to the acoustic detection of a leak in compressed air lines, the Gas Leak Detector shows the intensity of the ultrasound signal on a display. The sensor from the Gas Leak Detector has a laser pointer for better targeting of the pipes or pressure vessels. A lance can also be adapted to the sensor, which contributes to pinpoint leak detection. With the help of the Gas Leak Detector, depending on the operating pressure in the pipeline, the user can safely locate a leak from a distance of up to 18m, 59 ft. The Gas Leak Detector is operated with a rechargeable battery, which ensures that the Gas Leak Detector can be used for up to 6 hours. The Gas Leak Detector is delivered in a robust carrying case including all accessories.
