Dwyer Instruments 422-58CM Analog Pressure Gauge

Overview

The Dwyer Instruments 422-58CM Analog Pressure Gauge is a Series 422 Durablock inclined-vertical manometer with a double column and 6-1/2 inch inclined scale. It is designed for precision measurement of low differential pressures, with the inclined bore covering 0 to 5.5 cm H2O for sensitive low-range readings and the vertical column covering 7 to 58 cm H2O for higher pressures.

The 1-1/4 inch thick acrylic Durablock body is virtually unbreakable and free of distortion, and the 3/16 inch bores are accurate to +/-0.0002 inch so the instrument holds calibration without recalibration from distortion. A ground glass bubble level, selected gage oil with high wettability for a clean meniscus, and parallax-free reading against the polished aluminum scale support consistent, accurate results; an O-ring sealed plunger provides easy zero adjustment.

Features

  • Dual-range: 0-5.5 cm H2O inclined and 7-58 cm H2O vertical
  • Double-column Durablock design, 6-1/2 inch inclined scale
  • 1-1/4 inch solid acrylic body, virtually unbreakable and distortion-free
  • 3/16 inch bores accurate to +/-0.0002 inch
  • Parallax-free reading via meniscus reflection in polished aluminum scale
  • Ground glass bubble level for precise alignment
  • O-ring sealed fluid level plunger for easy zeroing
  • Selected gage oil forms a consistent, well-shaped meniscus

Applications

  • Laboratory and test-bench measurement of low differential pressures
  • Air filter monitoring and HVAC system balancing
  • Fan performance verification in ventilation and process air systems
