30 to 0 to 30 psi Compound Gauge

This compound gauge measures vacuum and pressure from 30 to 0 to 30 psi. The 3 1/2 inch dial provides clear readings for automotive and industrial testing. It suits technicians who need a single instrument for both negative and positive pressure ranges.

Bottom NPT connection installs directly

The 1/4 inch male NPT process connection threads into standard ports at the bottom of the case. No field filling is required and the dry dampening feature means no liquid handling. Acrylic lens and 304 stainless steel case resist workshop solvents and impact.

+/-3-2-3 percent accuracy class

Accuracy follows the +/-3-2-3 percent specification across the full scale. This tolerance determines whether the gauge meets your calibration requirements for vacuum and pressure testing. The white dial with silver case offers high contrast for quick visual checks.
