Product Description

Dwyer Series-2000 Magnehelic® Gauge can be flush or surface mounted with standard hardware like the Grouting box supplied. By default, the gauge is calibrated for vertical position, but it can also be configured by re-zeroing if the range is above 1″. However, for maximum accuracy, the Magnehelic® gauge must be calibrated in the same position in which they are used.

Features Of Dwyer Magnehelic® Gauge:

  • The undistorted plastic face makes the display easy to read and permits viewing from far away
  • Quick response to pressure changes with no delay in assessing critical situations
  • Durable and rugged housing
  • The high-accuracy option is twice as accurate as the standard Magnehelic® gauge. The bezel provides a flange for flush mounting in the panel.
  • The clear plastic face is highly resistant to breakage. It provides an undistorted viewing of the pointer and scale.
  • The precision litho-printed scale is accurate and easy to read.
  • The red-tipped pointer of heat-treated aluminum tubing is easy to see. It is rigidly mounted on the helix shaft.
  • Pointer stops of molded rubber prevent the pointer from crossing the setpoint causing no damage.
  • Calibrated range spring is flat spring steel. A small amplitude of motion assures consistency and long life. It reacts to pressure on the diaphragm. Live length adjustable for calibration.
