A leak standard (master) is a calibrated, simulated leak that can be used in circuit with the part under test. A leak standard can be used during test setup to help you determine the parameters for your leak test. It can also be used to challenge your system by comparing multiple leak systems to each other. Our leak standards are outfitted with Staubli quick couplers to allow easy inteface with our instruments. Each leak standard (master) is provided with a calibration report.
