Ashcroft 1188 Low Pressure Gauge

The Ashcroft 1188 is a low pressure gauge built for monitoring systems up to 100 psi. It features a 4 1/2 inch white dial housed in a black phenolic case with a glass lens. A 1/4 inch male NPT connection at the bottom allows direct installation into compatible pipework. Accuracy follows a +/-2-1-2 percent scale across the range.

Technicians measuring air or compatible gas pressure

This gauge suits technicians and engineers who need a bottom-connected, phenolic-cased instrument for low-pressure readings. The dial size supports clear viewing in panel or pipe-mounted positions. Buyers who require a filled case for vibration damping, an IP or NEMA rated enclosure, or a different process connection size should look at other models. Field fillable construction is not offered on this unit.

+/-2-1-2 percent accuracy specification

The +/-2-1-2 percent accuracy grade defines whether this gauge meets your measurement tolerance. It indicates the permitted error across the full 0 to 100 psi span, with tighter tolerance in the middle third of the scale. Verify that this accuracy class satisfies your calibration or process requirements before fitting the gauge. The 5.38 inch bolt circle diameter also determines panel mounting compatibility.

Questions about this item

How can I verify the gauge is reading correctly after installing it on a 1/4 in NPT connection?

Apply a known reference pressure and confirm the pointer stays within the stated +/-2-1-2 percent accuracy across the 0 to 100 psi range.

What comes with the Ashcroft 1188 gauge and what must I supply separately?

The gauge includes a 4 1/2 in phenolic case with glass lens and 1/4 in NPT male bottom connection; you must provide thread sealant and any required mounting hardware for the 5.38 in bolt circle.

Which pressure range version should I choose for low-pressure pneumatic testing up to 100 psi?

Select the 0 to 100 psi model, which matches the primary pressure range printed on the white dial of this low-pressure gauge.
