Compared with the prior art, the invention has the advantages of high detection precision, high intelligent degree and the like.

Description

technical field [0001] The invention relates to a filter detector, in particular to an integrity detector for a microfiltration membrane filter. Background technique [0002] When the filter integrity detector is tested, it first needs to measure the upstream volume of the filter, and then measure the pressure decay value in the filter, and calculate the gas flow rate of the filter. [0003] To automatically measure the upstream volume of the filter, generally a reference tank with a known volume is installed inside the detector, and the upstream volume of the filter is measured through a comparative test. [0004] However, after use, the moisture in the gas source usually remains in the reference tank, resulting in a decrease in the actual volume in the tank and affecting the accuracy of the measurement. Contents of the invention [0005] The object of the present invention is to provide an integrity tester for microfiltration membrane filters with high test accuracy and...
