Ashcroft 662876751222 Digital Pressure Gauge 2.5in Npt

Product Description

The ASHCROFT 662876751222 is a digital pressure gauge designed to measure vacuum pressure from 30 to 0 Hg VAC. It features a 2.5-inch diameter digital display housed in a black plastic case with stainless steel wetted parts and a polycarbonate lens. The gauge connects via a 0.25-inch NPT lower-mount fitting and carries an accuracy rating of 0.5% of scale, making it suitable for applications where precise vacuum readings are required. It is not liquid filled. Licensed HVAC technicians, plumbers, and instrumentation technicians are the typical installers for this type of gauge.

This gauge suits residential and commercial service applications requiring reliable vacuum measurement. The DG25 series digital format makes readings straightforward in low-light or fast-paced field conditions. The IP67 enclosure rating means the gauge can handle incidental water exposure and dusty environments. Its compact dimensions and lower-mount NPT connection allow it to fit into tight panel or line installations where analog gauges may be less readable.

Key Features

• Digital display with 0.5% of scale accuracy for precise vacuum measurement
• Stainless steel wetted parts resist corrosion in demanding service environments
• IP67-rated plastic case protects against dust ingress and temporary water immersion
• Polycarbonate lens provides impact resistance and clear readability
• Lower-mount 0.25-inch NPT connection for standard inline or panel installations
• Certified to CE, CRN, UL 61010, and cUL standards

Compatibility

Designed as an OEM-style or replacement digital vacuum gauge for systems using a 0.25-inch NPT lower-mount port rated for vacuum service within the -4 to 140 degrees F operating temperature range.

Installation Notes

Installation should be performed by a licensed technician familiar with pressure and vacuum instrumentation. Depressurize and isolate the system fully before removing or installing any gauge. Use appropriate thread sealant compatible with the process media on the NPT threads; do not overtighten, as plastic housings can crack under excess torque. Verify the operating temperature range of the installation environment falls within -4 to 140 degrees F before commissioning.
