Product introduction: The engine housing tightness tester - engine cylinder tightness detector is a differential pressure type air tightness detector that uses some non-toxic and non-corrosive inert gases such as dry and clean compressed air and nitrogen as the detection medium. It adopts high-precision gauge pressure sensors as the pressure sensitive element to perform leak volume detection on the detected products.

The spring tension testing machine for automobile is mainly used to test the strength of various coil springs and elastic elements, test the test force of springs and elastic elements under a certain amount of deformation, or test the residual height or deformation of springs and elastic elements under a certain test force.
