Medical device manufacturers and their supplies worldwide depend on InterTech Expertise
Mass Flow Leak Testing provides a direct measurement of leakage independent of pressure and volume. Faster shorter cycle times will produce an instantaneous measurement of flow at the end of stabilization. No further delays waiting for pressure decay. Mass flow leak testing can be used in both upstream and downstream modes, under pressure and vacuum conditions.
InterTech has pioneered this patented technology by developing a flow transducer that can measure leakage to less than 0.05 sccm, for test volumes from 1 cc to more than 5 liters while meeting GR&R of less than 5%.
Calibration is NIST traceable using a transfer standard such as a CalMaster or a calibrated orifice which can be connected to the panel mounted calibration port. A menu driven sequence results in the independent calibration of the instrument’s zero and span.
