Ashcroft 251009 Industrial Pressure Gauge 0-300 psi 2 1/2 in Stainless Steel

Ashcroft 251009 Gauge for Industrial Testing

The Ashcroft 251009 is a new industrial pressure gauge built for technicians who need reliable 0 to 300 psi readings in plant or field environments. Its 2 1/2 in dial with white face and +/- 1.00 percent accuracy supports clear measurement on hydraulic or pneumatic systems. The 304 stainless steel case and polycarbonate lens resist corrosion and impact in harsh conditions. A 1/4 in male NPT bottom connection fits standard process ports without adapters.

Sustained Accuracy Under Continuous Pressure

The gauge maintains its stated +/- 1.00 percent accuracy across the full 0 to 300 psi range during extended operation rather than only during brief checks. The field fillable design is not included, so the dry movement avoids fluid-related drift over long cycles. Electronic type construction provides stable output without mechanical wear that can degrade precision in high-cycle applications. The IP54 rating with plug vented and IP65 with plug closed ensure consistent performance when ambient conditions change during shifts.

Sealed Case Limits Dust and Water Ingress

The 304 stainless steel case meets NEMA 4 and IP65 when the vent plug is closed, preventing dust and water jets from affecting the movement during washdowns or outdoor exposure. With the plug vented the rating becomes IP54, still blocking harmful dust deposits while allowing pressure equalisation. No active cooling or power draw is required, so the gauge adds no thermal load or electrical noise to the panel. The polycarbonate lens resists cracking from vibration, keeping the seal intact in normal industrial use.
