Ashcroft 251009 100 psi Pressure Gauge

The Ashcroft 251009 is a 2 1/2 inch industrial pressure gauge built for measuring fluid or gas pressure up to 100 psi. Its 304 stainless steel case and polycarbonate lens provide corrosion resistance in harsh environments. A 1/4 inch male NPT bottom connection allows direct installation into compatible ports. Accuracy is rated at +/- 1.0 percent of span.

Suits panel builders needing IP54 or IP65 protection

This gauge suits engineers who require a bottom-mounted, field-ready instrument with NEMA 4 ingress protection when the vent plug is closed. The fixed dry dial and lack of vibration damping mean it is not intended for high-pulsation machinery or applications needing liquid-filled dampening. Buyers who need field-fillable cases or integrated dampening should look at alternative models.

Primary range 0 to 100 psi

The single specification that decides fit is the 0 to 100 psi primary pressure range. Systems operating above this limit will over-range the instrument, while processes needing finer resolution at lower pressures may require a gauge with a narrower span. Verify the maximum working pressure of your circuit matches this 100 psi upper bound before purchase.

Questions about this item

How can I verify the gauge reads correctly after installation?

Compare the needle position against a calibrated reference at several points across the 0 to 100 psi range; the stated accuracy is +/- 1.0 percent of full scale.

What comes with the gauge and what must I supply?

The gauge includes a 2 1/2 in dial, 1/4 in MNPT bottom connection, 304 stainless case, polycarbonate lens and IP54/IP65 rated vent plug; you must provide thread sealant and any required adapters.

Which pressure range and connection size should I select for a 100 psi system with 1/4 NPT ports?

Choose the 0 to 100 psi model with 1/4 in MNPT bottom connection — it matches both the required range and thread size.
