Value Brand 18C784 Low Pressure Gauge 0 to 30 psi 2 1/2 in Dial 1/4 in NPT measurement tool

SKU CH-28K2-NX3GM

Measures low pressure up to 30 psi with 1.5 percent accuracy on a 2 1/2 in dial and 1/4 in NPT connection

  • TypeElectronic
  • Accurate readings with ±1.5 % precision
  • Measures low pressure from 0 to 30 psi
  • Durable steel case protects the mechanism
  • Polycarbonate lens resists impact and cracking
  • 1/4 in NPT bottom connection fits standard fittings

Low-Pressure Gauge 0–30 psi

This gauge measures low-pressure systems from zero to thirty psi with a two-and-a-half inch dial. A copper-alloy diaphragm sensor and copper-alloy socket handle the process connection. The case is steel with a polycarbonate lens and the connection is a quarter-inch male NPT at the bottom.

Suited for steady low-pressure checks

Technicians verifying pneumatic or hydraulic circuits within the stated range will find the 1.5 percent accuracy adequate. It is not panel-mountable and carries no IP or hazardous-location rating, so installers needing sealed enclosures or classified-area approvals should look elsewhere.

Bottom-mount quarter-inch NPT fit

The male thread screws directly into a matching female port without adapters. Steel construction resists mechanical damage while the polycarbonate lens protects the dial face. No electrical supply is required, leaving the instrument ready for immediate mechanical installation.

Questions about this item

What fitting do I need on my system to connect the 1/4 in NPT male process connection?

You need a female 1/4 in NPT port or adapter on your piping so the gauge's male thread can screw directly into it.

Will the +/- 1.5 percent accuracy still be reliable if I keep using my older copper-alloy fittings?

Yes, the gauge's copper-alloy sensor and socket are compatible with existing copper-alloy fittings and the stated accuracy applies across the 0 to 30 psi range.

How can I verify the gauge is reading correctly after I install it?

Apply a known reference pressure within the 0 to 30 psi span and confirm the needle sits within +/- 1.5 percent of that value on the 2 1/2 in dial.
