◎ Leak standard(fixed flow generator)——constant pressure, constant leak rate, serves as the counterweight of leakage and it is mainly used for metrological transmission (traceability), equipment check, confirmation of operating condition leak rate, and benchmarking between upstream and downstream. We can provide customers with many types of leak standard.

◎ Calibrator——The volume change can be accurately produced by adjusting the calibration knob. It is mainly used for the volume measurement of the tested object, determination of test standards and verification of equipment sensitivity.

◎ Universal leak calibrator——Pressure and flow can be set arbitrarily within the range, that is, standard leak can be set, and multiple standard leak points can be set by one instrument, which solves the difficult problem of requiring multiple leak standard in the field.

◎ Leak Standard Calibrator——Used for rapid testing of leak standard. It can be used to test positive pressure, negative pressure and vacuum leak standard.

◎ Calibrator of Differential Pressure Leak Tester——It is convenient to switch between direct pressure and differential pressure for the calibration of sensor of differential pressure leak tester. The self-contained differential pressure generator can realize multi-point calibration.
