Ashcroft 251009 3000 psi 1.5% pressure gauge

Industrial pressure gauge for high-pressure systems

This Ashcroft 251009 gauge measures 0 to 3000 psi with a 1.5 percent accuracy rating. The 304 stainless steel case and polycarbonate lens resist corrosion in demanding environments. It is designed for technicians and engineers who need reliable local indication on hydraulic or pneumatic circuits.

Accuracy class that determines suitability

The +/- 1.5 percent full-scale tolerance is the critical specification for calibration planning and quality compliance. A tighter class would be required for laboratory reference work, while a wider class would risk unacceptable deviation in process control. Select this gauge only when the 1.5 percent window matches your documented procedure.

Sustained reading stability under vibration

Liquid filling dampens pointer flutter so the needle remains readable during continuous pump pulsation or machinery vibration. The IP54 rating with the vent plug open allows case breathing, while closing the plug raises protection to IP65 and NEMA 4 for wash-down conditions. This behaviour supports long shifts without the parallax errors that dry gauges develop under the same load.
