Medical device and medical supply manufacturers with applications requiring high speed leak testing of parts (from several cubic centimeters to several liter volumes) can now integrate leak testing into test-intensive assembly operations using the M-1075-Y mass flow leak detectors. The detectors feature a touch screen with intuitive menu-driven operator controls, embedded web pages allowing managers to monitor and access operations remotely, real-time display of all leak test stages, and Ethernet-connectivity making integration into existing factory networks seamless.
