【Product features】

1. Computer control, the pressure and detection time of the pipeline can be set according to different products, and the machine can be fully automated after setting.

2. Multiple test programs available in the software for selection, and different test programs can be chosen according to the actual test purpose.
a. Pressure stepless regulation;
b. Pressure relief safety protection;
c. Constant speed vacuum pumping - pressure holding - pressure relief;
d. Constant speed vacuum pumping - pressure holding - constant speed vacuum pumping - pressure holding - reaching 100KPa (Incremental vacuum pumping);

3. Vacuum pumping time and test pressure can be freely set, and single or multiple pressure holding tests can be set arbitrarily during the test process. The pressure increasing speed can be kept constant, and stepless adjustment.

4. Test data and curve parameters can be displayed in real-time, the test results can be automatically saved and stored, and the test report can be printed arbitrarily;
