Industrial pressure gauge 0–100 psi

The Ashcroft 251009 is a new 304 stainless steel instrument built for industrial test and measurement tasks. It covers a primary range of 0 to 100 psi with an accuracy of +/- 1.5 percent. The 2 1/2 in nominal dial uses a polycarbonate lens and a metallic case rated IP54 when vented or IP65 and NEMA 4 when the plug is closed. Process connection is a 1/4 in male NPT located at the bottom.

Accuracy class and environmental sealing

The +/- 1.5 percent accuracy defines the practical reading limit for calibration and monitoring work. The case achieves IP54 protection with the vent plug open and steps up to IP65 and NEMA 4 when the plug is closed, so the gauge survives wash-down and dusty environments only when sealed. The liquid-filled design adds vibration resistance without a separate dampening feature. The polycarbonate lens resists impact but is not rated for extreme chemical exposure.

304 stainless construction and bottom mount

The 304 stainless steel case and wetted parts suit corrosive media where carbon steel would fail. A bottom-mounted 1/4 in male NPT connection aligns with standard panel or pipe tee installations and the case is field-fillable for liquid top-ups. The gauge is not designed for panel-cutout flush mounting or surface brackets. Buyers who need a rear connection, a different pressure range, or a non-metallic case for chemical compatibility should look elsewhere.

Questions about this item

Should I choose the 0-100 psi range or a different range for my application?

This model is fixed at 0 to 100 psi. Select a different Ashcroft gauge if your system pressure exceeds or sits well below this span.

What does the ±1.5 % accuracy mean when the gauge is installed on equipment?

At full scale the reading can deviate by up to 1.5 psi. Across the 0-100 psi span the error stays within that same percentage band.

How does the 1/4 NPT connection and IP rating affect sealing and ingress protection?

The 1/4 in male NPT thread seals with tape or sealant. With the vent plug closed the case meets IP65 and NEMA 4; open it drops to IP54.
