AMT-600DF
The AMT-600DF Differential Flow Air Tightness Tester is a standard-grade seal leak detection instrument featuring a full-touchscreen design. While ensuring the core advantages of differential flow detection, it meets the batch testing needs of general industrial sectors for flow difference detection with a more economical configuration. It quickly and stably identifies measurement errors caused by air supply fluctuations, making it a practical choice for manufacturers seeking to improve flow-based testing accuracy. Through in-depth analysis of test data, the AMT-600DF not only accurately judges product quality but also helps enterprises optimize testing processes and reduce air source purification costs – delivering significant value in quality control. The AMT-600DF performs leak detection based on the differential flow method, a mature technology for solving flow testing challenges under unstable air supply conditions. The instrument integrates two high-precision flow sensors, which measure the real-time flow rates of the reference channel and the measurement channel respectively, and eliminates air supply fluctuation interference through differential calculation. During testing, both channels are pressurized simultaneously, and the instrument automatically calculates the flow difference, directly outputting the leak rate or flow deviation of the test workpiece. This method does not require an additional precision regulated air source, adapts to ordinary factory air supply environments, and provides good test repeatability. The leak resolution reaches 0.1 ml/min, meeting the flow difference detection requirements of most conventional products. A built-in pressure sensor simultaneously monitors system pressure to ensure safe testing.
