SKU CH-KSKE-70BE8

Electronic commercial vacuum gauge with 304 stainless steel case, 30 to 0 range and +/-3-2-3% accuracy

  • TypeElectronic
  • Accurate vacuum readings with +/-3-2-3% precision
  • Durable 304 stainless steel case resists corrosion
  • Clear white dial with acrylic lens for easy viewing
  • 1/4 inch NPT male connection fits standard fittings
  • Liquid-filled design dampens vibration for stable measurements

Zoro Select Commercial Vacuum Gauge

This Zoro Select gauge measures vacuum levels for commercial and industrial testing. It suits technicians who need a direct-reading instrument for system evacuation or leak checks. The 30 to 0 range covers common vacuum applications in HVAC and refrigeration work. Buyers who need positive-pressure readings or digital logging should choose a different instrument.

Stainless case with liquid-filled damping

The 304 stainless steel case resists corrosion in workshop environments. Liquid filling dampens needle vibration without external power or batteries. Acrylic lens protects the white dial while maintaining readability. No IP or NEMA rating is declared, so exposure to jets or immersion is not advised.

1/4 NPT male center-back connection

The gauge mounts directly into a 1/4 inch NPT female port with the connection at the center back. This orientation keeps the dial upright on panel or manifold installations. Field-fillable design is not offered, so the factory fill is permanent. Ensure your fitting matches the male NPT thread before ordering.

Questions about this item

How do I install the 1/4 in NPT male center-back connection on the Value Brand 4CFR2 gauge, and what step is often missed?

Thread the 1/4 in NPT male fitting into the matching female port using PTFE tape on the threads; the step often missed is tightening to a snug fit without over-torquing the 304 stainless steel case.

What maintenance or replacement will the 2 1/2 in dial vacuum gauge need later?

The acrylic lens can be cleaned with mild soap and water; the dry mechanism has no fill fluid to replace, so only periodic calibration checks against the +/-3-2-3% accuracy are required.

What limit appears first during sustained vacuum use on the 30 to 0 range gauge?

The +/-3-2-3% accuracy band is the first limit encountered; the dry dampening and non-liquid-filled design mean no thermal drift occurs, so accuracy tolerance governs sustained readings.
