Industrial pressure gauge 0-300 psi

This Ashcroft 251009 gauge measures pressure from 0 to 300 psi with a stated accuracy of +/- 1.0 percent. The 2-1/2 inch dial provides clear readings for industrial monitoring tasks. It suits technicians who need a direct-reading instrument for hydraulic or pneumatic systems.

Capacity and headroom

The primary range tops out at 300 psi, giving headroom for typical shop air and moderate hydraulic circuits. Accuracy holds at +/- 1.0 percent across the scale. The PLUS! Performance dampening steadies the pointer against vibration. Systems exceeding 300 psi or requiring tighter tolerance will need a different instrument.

Build quality and connections

The case uses 304 stainless steel with a metallic finish and a polycarbonate lens. A 1/4 inch male NPT lower-back connection mounts directly into panel ports. The gauge is field-fillable dry and carries IP54 when vented or IP65 and NEMA 4 when the plug is closed. Buyers needing a front-flange or bottom-stem mount cannot use this configuration.

Questions about this item

Will the 1/4 in NPT male connection on this Ashcroft 251009 gauge thread directly into the existing port on my older pump?

The gauge has a 1/4 in NPT male lower-back connection; if the pump port is also 1/4 in NPT female it will thread straight in, otherwise an adapter is required.

How can I verify the +/- 1.0 percent accuracy after I install the gauge?

Apply a known reference pressure from a calibrated source and compare the reading; the needle should stay within 1.0 percent of full scale across the 0 to 300 psi range.

Does the box include a vent plug for the IP54 rating or must I order it separately?

The IP54 rating applies when the vent plug is fitted; the plug is supplied with the gauge so no separate purchase is needed for that configuration.
