Ashcroft Process Gauge – P/N 451279-P-SH-04-B-XC4-LL-NH-SG-300#

The Ashcroft 1279 Series Process Gauge is a premium-grade pressure measurement instrument designed for critical and corrosive process applications requiring high accuracy, durability, and full traceability. Engineered for demanding industrial environments, it delivers reliable performance in oil & gas, chemical processing, marine, and offshore installations.

This configuration features a K-Monel® 500 bourdon tube with Monel® 400 process connection, providing outstanding resistance to seawater, acids, and other highly corrosive media. It is ideally suited for severe service conditions where standard stainless steel materials may not be sufficient.

The gauge is constructed with a solid-front, dry case design with hermetic sealing, enhancing safety and environmental protection by preventing ingress of moisture and contaminants while also providing added protection in the event of overpressure.

Equipped with a ½” NPT male back connection, the unit ensures easy installation and compatibility with standard piping systems. The PLUS! Performance option (LL) enhances overall accuracy, stability, and long-term reliability under fluctuating process conditions.

This model includes EN 10204 3.1 traceable calibration certification (XC4) for full quality assurance, along with a stainless steel identification tag (NH) for clear asset tracking and tagging compliance. The gauge is also fitted with a safety glass lens (SG) for improved durability and operator safety.

With a pressure range of 0–300 psi, this instrument is optimized for low-to-medium pressure applications requiring high corrosion resistance and dependable measurement accuracy.
