Precision Process Gauge

The Zoro Select 11A483 is a process vacuum gauge built for technicians who need accurate negative-pressure readings on pressure-washer systems and similar equipment. Its +/-0.5% accuracy and 30-to-0 range suit calibration, troubleshooting and routine monitoring tasks.

Bottom-Mount NPT Integration

A 1/4-inch male NPT connection at the bottom lets the gauge thread directly into a pump port or manifold without extra adapters. The cast-aluminium case and glass lens withstand shop environments, while the dry, non-fillable design avoids liquid leaks and reduces mounting restrictions.

Vacuum Range and Limits

The dial spans 30 to 0 inches of mercury, giving clear visibility across the full vacuum band the gauge is rated for. It does not measure positive pressure, so systems that cycle above atmosphere need a separate instrument. The lack of vibration damping or an IP rating means it is best suited to stable, indoor installations.

  • Accurate vacuum readings with ±0.5% precision
  • Clear 4½-inch white dial for easy monitoring

Questions about this item

How does the +/-0.5% accuracy hold up during continuous vacuum monitoring?

The gauge maintains its stated +/-0.5% accuracy across the full 30 to 0 range thanks to its cast aluminum case and glass lens, with no liquid fill to degrade over time.

Will the cast aluminum case and glass lens run hot or make noise during all-day operation?

The mechanical gauge has no moving electronics, so it generates no heat or noise; the cast aluminum case simply dissipates ambient temperature.

What process connection must my system already have for this gauge to thread in?

Your system needs a female 1/4 in NPT port at the bottom mounting point to accept the gauge's male connection.
