GAS FLOW CALIBRATOR
Cal=Trak XL primary standard gas flow calibrator, for flows up to 500 slpm, has an accuracy of ±0.25%. In either manual or automatic operation the calibrator measures, displays and outputs the flow of gas. Users may select from mass or volumetric flow so that a variety of flow devices can be validated or calibrated. The menu-driven configuration of the calibrator allows end-users to customize the calibrator to fit their changing needs.
