DP3115B series is an air tightness tester developed for the new energy vehicle industry. It adopts multi-channel differential pressure design, which is less affected by external factors, high test accuracy and good long-term stability. It uses color touch screen display, supports setting parameters and test data saving, test pressure programmable setting, and equipped with PC and PLC interface.
DP3115B is a differential pressure air tightness tester used to check the air tightness of various components and finished products, which can improve the leak detection ability and realize the automation of the inspection station. This instrument is equipped with a high-sensitivity differential pressure sensor and a pneumatic valve that is not affected by heat, and the operation of the pneumatic valve and the sensitivity of the sensor are automatically checked in each test. The basic circuit is composed of a self-test function with excellent function and safety, and the test capability and test time are shortened by using the standard error correction and setting function, or the error reduction function. It is fit for a wide range of test products and can accurately display the test pressure, differential pressure, and leakage amount.
