Industrial Pressure Gauge 0-30 psi

This industrial pressure gauge measures from 0 to 30 psi with a 4 1/2 in dial and 1/4 in NPT bottom connection. The gauge case is stainless steel with an acrylic lens. Accuracy is +/- 1.0 percent. Sensor and socket materials are copper alloy. It is designed for non-explosive gas or liquid that does not crystallize or corrode copper alloy.

Suited for General Industrial Monitoring

This gauge suits technicians monitoring compatible gas or liquid systems within the 0 to 30 psi range. It is not rated for hazardous locations and carries no IP or NEMA rating. Buyers who need a gauge for explosive media, corrosive fluids, or certified hazardous-area installations should look at alternative instruments.

Consistent Accuracy Under Sustained Load

The +/- 1.0 percent accuracy specification applies across the operating range during continuous use. Copper alloy wetted parts resist corrosion from compatible media, supporting stable readings over time. The stainless steel case protects the mechanism in typical industrial environments without additional environmental sealing.

Questions about this item

What fitting do I need on my system for the 1/4 in NPT male connection to seal properly?

You need a female 1/4 in NPT port on the pipe or vessel so the gauge's male thread can engage directly.

Will the copper alloy sensor and socket hold up if I keep using this gauge on the same non-corrosive gas line I have now?

Yes, the copper alloy HPb59-1 sensor and socket are rated for non-explosive gas or liquid that does not crystallize or corrode copper alloy.

How can I verify the gauge is reading within its rated accuracy after I install it?

Apply a known reference pressure and confirm the pointer stays within ±1.0 % of the 0 to 30 psi scale across the range.
