Low-Pressure Gauge 0 to 5 psi

This 2 1/2 inch dial gauge measures low-pressure media up to 5 psi with a stated accuracy of ±1.5 percent. A copper-alloy diaphragm sensor and matching socket handle the process connection. The steel case and polycarbonate lens protect the movement in general-purpose use.

Suits technicians reading low-pressure air

The centre-back 1/4 NPT male connection fits panel cut-outs but the gauge is not panel-mountable. Buyers needing a flange or clamp mounting style should look at a different model. The gauge carries no IP or NEMA rating, so it is not suited to wash-down or hazardous-area environments.

Accuracy ±1.5 percent full scale

This single figure determines whether the instrument meets the test or calibration tolerance required for the job. If the application demands tighter error limits, a higher-grade gauge must be selected.

Questions about this item

Which pressure range should I select for my low-pressure system?

This gauge measures from zero to five psi, so choose it when your working pressure stays inside that span.

What does the stated accuracy mean once the gauge is installed?

Readings will stay within plus or minus one point five percent of the full five-psi scale under normal conditions.

How does the quarter-inch NPT connection limit installation options?

The male centre-back fitting threads directly into a matching female NPT port; no panel-mount hardware is included.
