Pressure Gauge 0-6000 psi

The Miller-Smith Equipment GA145-03 is a new electronic pressure gauge designed for welding regulator applications. It measures from 0 to 6000 psi with a secondary scale of 0 to 400 bar. The 2-inch steel case features a black finish and brass or bronze wetted parts. Accuracy is rated at +/-3-2-3 percent with numbered graduations every 1000 psi and smallest graduations of 200 psi.

1/4 Inch MNPT Bottom Connection

This gauge suits technicians monitoring high-pressure welding systems who need a bottom-mounted 1/4 inch MNPT connection. It is not panel mountable and is not liquid filled. Buyers requiring panel mounting or a liquid-filled case for vibration damping should look at alternative models.

+/-3-2-3 Percent Accuracy Grade

The +/-3-2-3 percent accuracy grade determines if this gauge meets the precision requirements for your specific welding or testing procedures. No calibration certificate is included with the unit. Verify this tolerance against your process specifications before purchasing.

Questions about this item

How much heat does the Miller-Smith GA145-03 generate during all-day use on a welding regulator?

The gauge is a mechanical, liquid-free instrument with no power source, so it produces no measurable heat while reading pressures up to 6000 psi.

What thread must my regulator already have for this 1/4 in MNPT gauge to seal correctly?

The gauge requires a matching 1/4 in FNPT port on the regulator or panel for a proper connection.

Will the +/-3-2-3 percent accuracy hold when I keep my older brass-bodied regulator in the same line?

Yes, the brass/bronze wetted parts are compatible with legacy brass regulators and the stated tolerance applies across the full 0-6000 psi range.
