  • +/- 1.5 percent accuracy ensures reliable readings across the full scale

Industrial Compound Gauge

The Ashcroft 351009 is a new industrial compound gauge designed for technicians who need to measure both vacuum and positive pressure in a single instrument. Its 3 1/2 in nominal dial displays a primary range of 30 to 0 to 15 psi with an accuracy of +/- 1.5 percent. The 304 stainless steel case and polycarbonate lens suit harsh environments where durability matters.

Installation Checks

Verify that your system uses a 1/4 in male NPT process connection at the bottom mounting location before ordering. The gauge is field fillable and offers two ingress ratings depending on the vent plug state: IP54 when vented and IP65 when the plug is closed. Ensure the metallic case color and connection orientation match your panel layout requirements.

Sustained Load Behaviour

The liquid-filled dampening provides continuous vibration resistance during prolonged operation, keeping the pointer steady without a dry dampening feature. The IP65 rating with the plug closed maintains protection against dust and water jets over extended shifts. Stainless steel construction resists corrosion through long-term exposure to process media.

Questions about this item

Does the Ashcroft 351009 arrive ready to install or do I need to buy a NPT fitting separately?

The gauge has a male 1/4 in NPT bottom connection built in, so it threads directly into a matching female port; no extra fitting is required unless your system uses a different thread.

Should I choose the vented IP54 setting or the sealed IP65 NEMA 4 setting for a wash-down area?

With the plug closed the gauge meets IP65 and NEMA 4 for wash-down protection; open the vent plug only if you need IP54 pressure equalisation.

What does the +/- 1.5 % accuracy figure mean when the needle reads 10 psi on the 30 to 0 to 15 psi scale?

Accuracy is +/- 1.5 % of the full scale span, so at any reading — including 10 psi — the true pressure is within +/- 1.5 % of the total range.
