Commercial Vacuum Gauge 2 in

The Zoro Select commercial vacuum gauge measures pressure from 30 to 0 using a 2 in dial housed in a 304 stainless steel case. It is built for technicians who need a straightforward mechanical instrument for vacuum systems in automotive or industrial settings.

Accuracy class +/-3-2-3%

The gauge carries an accuracy rating of +/-3-2-3 percent across its scale. This single specification determines whether the instrument meets the tolerance required for a given calibration or test procedure.

1/4 in NPT male bottom connection

The process connection is a 1/4 in NPT male thread located at the bottom of the case. The acrylic lens and white dial provide clear reading, while the dry dampening and lack of vibration resistance mean the gauge suits steady, low-shock installations. It is not field fillable and carries no IP or NEMA rating.

Questions about this item

What does the +/-3-2-3% accuracy figure mean when the gauge is reading vacuum on a real system?

The gauge is accurate within +/-3% of full scale at the 30 inHg and zero ends, and within +/-2% across the middle portion of the dial.

What does the 1/4 in NPT male process connection allow me to do in practice?

It threads directly into a 1/4 in NPT female port on equipment or piping without needing an adapter.

What mounting clearance does the 2 in dial with bottom connection need?

The 2 in stainless steel case with bottom-mounted 1/4 in NPT connection requires enough space below the dial for the fitting and wrench access.
