Ashcroft 1188S Low Pressure Gauge 0-30 psi

The Ashcroft 1188S is a low pressure gauge designed to measure from 0 to 30 psi. It features a 4 1/2 inch dial housed in a black phenolic case with a glass lens. A male 1/2 inch NPT connection at the bottom mounts the gauge directly into the process line. The white dial provides clear readings for industrial monitoring tasks.

Suits technicians monitoring low-pressure air

This gauge suits technicians who need a direct-mount instrument for low-pressure air or gas lines. The phenolic case resists corrosion in harsh environments. Buyers who need a filled gauge to dampen vibration should look elsewhere. Applications requiring an IP or NEMA rated enclosure for wash-down duty are not supported by this model.

Accuracy class +/-2-1-2 percent

The gauge offers an accuracy class of +/-2-1-2 percent of span across the 0 to 30 psi range. This specification determines whether the instrument meets the precision requirements for a given calibration or process control standard. The bolt circle diameter measures 5.38 in for panel mounting reference. Verify this tolerance against your system documentation before installation.

Questions about this item

What NPT thread size must my piping have to connect the 1/2 in NPT male process connection?

Your piping needs a 1/2 in NPT female thread to mate with the gauge's male process connection.

Will the 4 1/2 in dial and phenolic case fit within a standard 5.38 in bolt-circle panel cut-out?

Yes, the gauge's 5.38 in bolt circle diameter matches that panel cut-out for direct mounting.

How can I verify the +/-2-1-2 percent accuracy is holding after installation?

Apply a known reference pressure within the 0 to 30 psi range and confirm the pointer reads within the stated tolerance.
