Pressure gauge with black steel case and white gray face showing 0 to 30 psi and 0 to 2 Bar

Miller-Smith Equipment

Miller-Smith Equipment GA141-03 Pressure Gauge 0-30 psi 0-2 Bar

SKU CH-5QZS-0VF95

Measures 0-30 psi and 0-2 bar with ±3-2-3% accuracy for welding regulator use

  • TypeElectronic
  • Measures up to 30 psi for precise low-pressure welding tasks
  • Dual-scale dial shows 0-2 Bar for metric compatibility
  • +/-3-2-3% accuracy class delivers reliable regulator readings
  • Steel case with brass wetted parts resists corrosion in shop environments
  • 1 psi graduations allow fine adjustment of shielding gas flow

Purpose and user

The Miller-Smith Equipment GA141-03 is a new pressure gauge built for welding regulator setups. It reads zero to 30 psi primary and zero to 2 Bar secondary with a stated accuracy of plus or minus three-two-three percent. The brass and bronze wetted parts suit inert and mild reactive gases in shop or field use.

Case and connection details

A black steel case houses the 2 in dial behind a white and gray frame, while the blow-moulded polyethylene body protects the movement from knocks. The quarter-inch male NPT bottom mount threads directly into regulator ports without extra adapters. No panel-mount hardware or liquid fill is included, so vibration damping relies on the regulator body itself.

Installation notes

Thread the gauge by hand then snug with a wrench on the hex flat; over-tightening distorts the brass seat and causes leaks. The bottom entry means condensation can collect behind the lens if the regulator sits low — mount the assembly upright where possible. No calibration certificate ships with the unit, so verify against a known reference before critical work.

Questions about this item

Will the gauge need recalibration or replacement parts over time?

The gauge ships without a calibration certificate and uses a steel case with brass/bronze wetted parts; no user-serviceable components are listed, so long-term maintenance would be limited to verifying accuracy against a known reference.

What accuracy limit appears first during continuous welding regulator use?

The stated tolerance is ±3-2-3 percent of full scale across the 0-30 psi primary range, so that percentage band is the limiting factor for sustained readings.

How much heat or noise does the gauge produce when mounted on a regulator all day?

As a purely mechanical, liquid-free instrument with no moving electronics, it generates no audible noise and negligible heat during continuous operation.
