Description
The Ralston Instruments NPAK-0000-0-0 is a portable pressure generation kit that uses a refillable nitrogen cylinder as its source. A pressure-balanced fine adjustment piston lets the operator set pressure precisely anywhere from very low values up to 3000 psi, without hand pumping. The kit packs the regulator, controls and a storage area for a reference test gauge into one case, and connects through Ralston Quick-test fittings that seal by hand. Instrument technicians in oil and gas, utilities and process plants use it to check and calibrate pressure gauges, switches and transmitters in the field.
Key features
- Nitrogen cylinder source for high pressure without manual pumping
- Pressure-balanced fine adjustment piston with fingertip control
- Controllable from 0.03 psi (2 mbar) up to 3000 psi (207 bar)
- Storage compartment in the control panel for a reference test gauge
- Quick-test hose and adapters connect without thread sealant or wrenches
- Optional padded strap for field carrying (NPAK-STRP)
Typical applications
- Field calibration of pressure gauges and transmitters
- Testing pressure switches and safety devices
- High-pressure checks on pipelines and wellhead instrumentation
- Leak and hold testing of small pressure systems
