Compound gauge for vacuum and pressure

The Ashcroft compound gauge measures both vacuum down to -30 in Hg and pressure up to 30 psi on a single dial. It is built with a 304 stainless steel case and wetted parts for corrosion resistance. The instrument is cleaned for oxygen service and intended for panel mounting in industrial or laboratory systems.

Replaces gauges with limited range or carbon steel

A single compound gauge replaces separate vacuum and pressure instruments where both readings are needed. The 304 stainless steel construction upgrades from carbon steel or brass models when the process media attacks those materials. The +/- 1.00 percent accuracy class suits general monitoring rather than precision calibration tasks.

Verify connection and range before ordering

Confirm the 1/4 in MNPT lower back connection matches the process tapping and panel cut-out. Ensure the -30 to 30 in Hg/psi scale covers the full operating envelope of the system. No calibration certificate is included, so arrange traceable calibration if your quality system requires it.

Questions about this item

What size thread does the 1/4 in MNPT lower-back connection on the Ashcroft 251009SW02BX6BV/30 gauge require?

The gauge uses a 1/4 in MNPT thread on its lower-back connection; match that thread size when fitting it to your system.

How is the Ashcroft 251009SW02BX6BV/30 gauge mounted, and what common mistake should be avoided?

The gauge is not panel mountable; install it directly into a 1/4 in MNPT port and do not attempt to secure it through a panel cut-out.

Does the Ashcroft 251009SW02BX6BV/30 gauge need any periodic fluid replacement or recalibration?

The gauge is not liquid filled and no calibration certificate is included, so it does not require fluid replacement; schedule recalibration based on your own quality procedures.
