How about Chongqing Qi 'ang airtight leak detector?

Air tightness detector (also known as leak detector, air tightness detector, leak detector, dry detector and leak detector) The traditional method to detect the air tightness (also known as leakage) of test pieces is to use the visual bubble method soaked in water or oil. The equipment is simple and the results are intuitive, but the detection accuracy and efficiency are low, and human factors have great influence, so it is impossible to realize automatic quantitative leak detection. At the same time, it will also bring adverse effects on the surface of the specimen, such as wet rust, impurity immersion, cumbersome water adhesion and so on.

The air tightness detector adopts the latest foreign microcomputer chip, high-precision sensor and zero-leakage solenoid valve to ensure the accuracy of detection and the durability of the instrument. Microcomputer automatically controls the detection process and collects data, and adopts the latest algorithm and special software to analyze and process the data, which compensates the influence of temperature (including environmental temperature) in the detection process to the greatest extent. It overcomes external interference, realizes direct differential pressure leak detection, has intuitive detection results and high cost performance, and is an ideal equipment for many air tightness tests.
