Ralston NPAK-0000-0-0 Pressure Source – Nitrogen
The NPAK-0000-0-0 Nitropak is a portable, self-contained nitrogen pressure source designed for calibration of differential and static pressure instruments. It incorporates an on-board refillable nitrogen cylinder, regulator, and precision volume controller to deliver stable, controllable pressure from near vacuum up to 3000 psi (210 bar).
The NPAK-0000-0-0 Nitropak is a portable, self-contained nitrogen pressure source designed for calibration of differential and static pressure instruments. It incorporates an on-board refillable nitrogen cylinder, regulator, and precision volume controller to deliver stable, controllable pressure from near vacuum up to 3000 psi (210 bar). A pressure-balanced fine adjustment mechanism enables ultra-fine control (≈0.0005 psi resolution), making it suitable for high-accuracy calibration tasks. The unit features quick-test connections, integrated pressure gauges, and overpressure protection, all housed in a rugged, field-portable enclosure.
