For a 0–30 PSI dry-gauge requirement, 80512 provides a 1-1/2 in dial and center back mounting style. A 1-1/2-inch dial minimizes the gauge footprint while still preserving a dedicated pressure scale.The 0 to 30 PSI scale is aimed at low-pressure monitoring, where a higher-range gauge would spread the useful reading over a smaller portion of the dial.This gauge uses a 1/8 in center-back connection rather than a lower connection, so the mounting orientation should be confirmed before replacement. The gauge uses Midland's standard dry-gauge construction: steel case, brass connections, and a plastic lens.As a dry pressure gauge, this model is intended for installations where a liquid-filled movement is not required. Gauge type should be confirmed along with pressure range and mounting position. Match all four primary selection points—range, dial size, connection size, and mounting style—to the equipment rather than relying on appearance alone.
