Altitude Pressure Gauge 0 to 140 psi

The Value Brand 18C810 is an altitude pressure gauge built for technicians who need to measure pressure in feet of water or mercury. It covers a range of 0 to 140 psi with a stated accuracy of ±1.0 percent. The 4 1/2 in dial uses a plastic lens and a stainless steel case. A copper sensor and socket connect via a 1/4 in male NPT bottom port.

Replaces worn analogue gauges

This unit replaces an ageing gauge when the dial has become hard to read or the calibration has drifted beyond the ±1.0 percent tolerance. The jump is worth it when the process temperature swings between -40 °F and 140 °F and the installation cannot accommodate a panel-mount design. It is not for buyers who need an IP or NEMA rated enclosure or a hazardous-location rating.

Copper sensor holds calibration

The copper sensor and socket resist corrosion from the media, helping the gauge hold its ±1.0 percent accuracy over long shifts. The stainless steel case protects the movement from knocks and vibration in industrial settings. Because the gauge carries no IP or NEMA rating, it should be shielded from direct wash-down or immersion. It is not for operators who require a certified hazardous-location instrument.

Questions about this item

What size NPT fitting does the 1/4 in process connection require?

The gauge uses a 1/4 in male NPT connection, so it threads directly into a matching female NPT port without an adapter.

Which step is often missed when installing the gauge with its copper sensor and socket?

Apply thread sealant to the male NPT threads before tightening to prevent leaks, as the copper socket can deform if over-torqued without sealant.

When should the gauge be checked for drift given the +/- 1.0 Percent accuracy spec?

Verify calibration annually or after any over-pressure event, since the +/- 1.0 Percent tolerance can shift if the copper sensor experiences pressure spikes beyond 140 psi.
