Ruhr (Luer) joint performance comprehensive tester:

Equipped with a 7-inch K600 kernel/dot matrix 65-color 800*480 resolution touchscreen display, English menu display, test parameters, production unit, production batch, tester, and other information can freely entered and automatically stored upon power failure; overload alarm and shutdown protection; multi-level password permission protection can be selected. Touch control is used to select the nominal capacity the syringe, and during the testing process, the axial force applied during assembly, torque, holding time, internal water pressure, separation force, and positive/negative leakage rate are displayed, and the test results can be printed by the onboard printer.
