Description
The Ralston QTVC-3KPSIG-FL is a pressure calibration kit that pairs the QTVC volume controller with a 3000 psi FieldLab digital gauge. The controller uses a pressure-balanced fine adjustment piston and soft-seated fill, balance and vent valves, which let a technician set very low or high pressures by hand with small, controlled steps. Quick-test hoses and fittings connect to the device under test without thread sealant or tools. Instrument technicians use the kit to check gauges, transmitters and switches on the bench or in the field.
