Low Pressure Compound Gauge 30 to 0 to 30

The Ashcroft 1188A is a low-pressure compound gauge designed to measure vacuum and pressure in a single instrument. It covers a range of 30 to 0 to 30 with an accuracy of +/-2-1-2 percent. The phenolic case and glass lens suit industrial environments where durability matters. Process connection is 1/4 inch NPT male located at the bottom.

Suits technicians needing vacuum

This gauge serves technicians who require both vacuum and positive pressure indication on one dial. It is not suitable for applications requiring a filled case for vibration damping or an IP-rated enclosure for wash-down environments. Builders needing a digital output or data logging capability should look at a different instrument type.

Primary pressure range 30 to 0 to 30

The defining specification is the primary pressure range of 30 to 0 to 30. This compound scale confirms the gauge handles both vacuum and low pressure within a single sweep. Verify that this exact range matches the system requirements before installation.

Questions about this item

What pressure range does the Ashcroft 1188A gauge measure, and how is that range expressed?

The gauge covers a compound range from 30 inches of mercury vacuum through zero to 30 psi pressure, allowing a single instrument to read both suction and positive pressure.

What size and thread type is the process connection on the Ashcroft 1188A?

It uses a male 1/4 inch NPT connection located at the bottom of the case, so it threads directly into a matching female port without an adapter.

How is the Ashcroft 1188A mounted, and what common step is missed during installation?

The gauge installs by threading the bottom male NPT fitting into the process port; the step often missed is applying suitable thread sealant to ensure a leak-free seal.
