This manual pressure testing machine has an automatic pressure retention function. Once the preset test pressure is reached, it will automatically maintain the pressure. However, during the pneumatic testing process, you need to manually time and manually release the pressure. The air leak tester whether the workpiece has leakage by filling high-pressure gas into the interior of the tested workpiece and monitoring its pressure changes in real time or by using intuitive bubble observation as an aid. The leak tester machine is equipped with an efficient gas pressurization system that can provide a test pressure of up to 80 MPa, meeting the pressure resistance and sealing test requirements of most industrial products. Its core feature lies in manual control and manual interpretation, ensuring the basic accuracy of the test while significantly reducing the cost of equipment purchase and maintenance.

First, set the test pressure. Then, the air leakage tester will increase the gas pressure to the preset level and inject it into the object being tested. Finally, the instrument will automatically maintain the pressure. Leak testing can be determined by the bubble method, pressure drop method, or pressure difference method. The bubble method leak detection involves immersing the object in water. If there are no bubbles in the water, the air tightness test is considered successful; otherwise, it is not. The pressure drop method leak detection involves observing the pressure gauge during the test to check the pressure drop. If the pressure drop is within the allowable range, the air pressure test is considered successful; otherwise, it is not.
For the manual air pressure tester, you need to set the test pressure by adjusting the air regulator. This instrument has an automatic pressure retention function, but you need to manually time to control the retention time. Additionally, you also need to manually determine the test results.
