Ashcroft 451279SS04LXLLVAC/30 Process Compound Gauge 30 to 0 to 30 psi 4 1/2 in

Ashcroft 4 1/2 in Process Compound Gauge

This Ashcroft gauge measures vacuum and pressure from 30 to 0 to 30 psi with a 4 1/2 inch dial. The phenolic case and glass lens protect the movement in demanding process environments. A 1/2 inch male NPT bottom connection mounts directly into piping systems. Dry PLUS! Performance dampening resists vibration without liquid fill.

For technicians monitoring vacuum

Suits operators who need a single instrument for compound ranges in hydraulic or pneumatic service. The +/- 0.5 percent accuracy meets standard calibration requirements. Not for installations requiring IP-rated enclosures or liquid-filled damping. Buyers needing field-fillable cases or panel-mount configurations should consider other models.

30 to 0 to 30 psi compound range

The primary specification is the dual-scale range covering both vacuum and pressure up to 30 psi. This span determines whether the gauge matches the process conditions. Confirm the range fits the system's maximum vacuum and pressure before ordering.
