Series 500 devices can be used as stand-alone units or as part of a system in machine lines or manufacturing plants. The intuitive menu structure allows for both simple operation of the unit and measurement curve display. As with the other device families, you can select different leak test methods and pressure sensors (pressure decay/pressure rise, relative pressure/differential pressure and mass flow methods). The Series 500 can also be used to measure volumetric flow. External sensors, pressure regulators and valves can be connected or controlled using the optional CAN bus module.
