Gas Tightness Leak Detector product price is unstable, usually about five figures.
Gas tightness tester (also known as leak tester, gas tightness meter, leak detector, dry tester, leak tester) the traditional test specimen sealing (also known as leakage) is used to soak the water or oil visual bubble method, it is simple equipment, the results are intuitive, but the detection of precision and efficiency is low, the influence of human factors is large, and can not be realized automatically and quantitatively leak detection. At the same time will bring the workpiece wet rust, impurities immersed in the adverse effects and cumbersome specimen surface attached to water (or oil) post-treatment, and even some products are not allowed to use this method of detection.
Automatic computer control of the detection process and data acquisition, the use of the latest algorithms and specialized software to analyze the data processing, the maximum degree of compensation for the detection process of temperature (including ambient temperature) and other effects. Overcome the external interference, realize the direct pressure difference leakage detection, detection results intuitive, with a high performance-price ratio, is the ideal equipment for many airtight detection.
Working Principle of Airtightness Leak Tester
Airtightness Leak Tester is mainly used to judge whether there is leakage of the package by filling the package with air under a certain pressure, and then detecting the change of the air pressure on the outer surface of the package. During the inflation process, the device monitors the pressure change inside the package in real time through the pressure sensor. After waiting for a period of time, the device again monitors the pressure inside the package, and if the pressure does not drop, it indicates that there is no leakage in the package. If the pressure drops, it indicates that there is a leak in the package.
Depending on the type of leak tester, the working principle may be slightly different, but the overall detection principle is similar. Packaging leak testers usually have high measurement accuracy and can accurately detect whether there is a leak in the package, which can effectively ensure the quality of food packaging.
