Purpose-built digital test gauge

The Ashcroft 302074 is a digital test pressure gauge built for technicians who need precise field readings. It measures from 0 to 300 psi with an accuracy of +/- 0.25 percent across the full range. A 3 in dial displays values in multiple engineering units including bar, kPa and psi. The instrument runs on two AA batteries for portable operation.

Construction and environmental rating

The gauge case and sensor are made from stainless steel while the socket uses 316 stainless steel for corrosion resistance. A polyester lens protects the display and the assembly carries an IP65 rating against dust and water jets. The diaphragm sensor connects via a male NPT process connection located at the bottom. These materials suit industrial and hydraulic environments where durability matters.

Accuracy class defines suitability

The +/- 0.25 percent accuracy class is the single specification that determines whether this gauge meets your test protocol. Calibration labs and quality departments should verify this tolerance against their procedure requirements before purchase. It is not rated for hazardous locations so it cannot be used in classified explosive atmospheres. Applications demanding higher precision or intrinsic safety need a different instrument class.

Questions about this item

Will the 3 in dial fit the panel cut-out on my existing test bench?

The nominal dial size is 3 in and the case is stainless steel, so it matches standard 3-inch panel openings.

How do I verify the ±0.25 % accuracy after installation?

Apply a known reference pressure up to 300 psi and confirm the reading stays within ±0.25 % of full scale across the selected unit.

Are the two AA batteries included or must I buy them separately?

The gauge requires two AA batteries for operation; the supplier data does not confirm they are supplied in the box.
