Capable of gas seal testing under pressures up to 120 MPa, meeting high industry standards;
Uses quantitative helium molecular permeation rate to describe gas tightness, ensuring accuracy of test results;
Single-point test time is only 1.5 minutes, providing high testing efficiency;
Simultaneous testing of tubing (casing) couplings at both the mill-end and field-end connections, making results more authentic and reliable.
