Value Brand Test Pressure Gauge 2-1/2 In 304 Stainless Steel

SKU CH-TF8N-DRTP8

2-1/2 inch stainless steel test pressure gauge with 304 case and 316 sensor for general-purpose measurement

  • TypeElectronic
  • +/-3-2-3% accuracy for reliable readings
  • 304 stainless steel case resists corrosion
  • 316 stainless steel sensor handles harsh media
  • 1/4 in NPT male bottom connection fits standard ports
  • Acrylic lens protects dial from damage

General Purpose Dial Gauge

This 2-1/2 inch general purpose dial pressure gauge is built for technicians who need a straightforward reading tool. The 304 stainless steel case and acrylic lens protect the mechanism in everyday workshop conditions. It arrives new and ready for installation on compatible systems.

1/4 Inch NPT Male Bottom Connection

The gauge installs directly onto a 1/4 inch NPT female port with its male bottom connection. Because it is not panel-mountable, it fits inline piping or manifold arrangements rather than dashboard cutouts. The 316 stainless steel sensor and socket resist corrosion from the measured media.

+/-3-2-3 Percent Accuracy Across the Scale

Accuracy follows the +/-3-2-3 percent grade, meaning the middle half of the scale reads within two percent while the ends allow three percent. The gauge carries no IP or hazardous location rating, so it suits general commercial use rather than sealed or classified environments. California Proposition 65 warnings apply for listed chemicals.

Questions about this item

At what pressure does the +/-3-2-3% accuracy limit become the deciding factor during extended testing?

The gauge maintains its stated +/-3-2-3% accuracy across the full operating range, so the limit applies from the first reading and does not shift with sustained use.

How hot does the 304 stainless steel case get when the gauge runs continuously at full scale?

The 304 stainless steel case and 316 stainless steel sensor are rated for the process temperature of the media being measured; the gauge itself generates no heat and has no internal power source.

Which NPT thread size must the existing port provide for the 1/4 in male bottom connection to seal?

The gauge requires a female 1/4 in NPT port at the mounting point to match its male bottom connection.
