Dwyer 2000 Magnehelic Differential Pressure Gauge

The Dwyer 2000 Magnehelic Differential Pressure Gauge is an IP67 rated highly reliable and robust instrument for measuring air and non-combustible gases. Features a 4 ̋ dial face and accuracy within ±2% of full scale. For applications requiring greater precision, the –HA High Accuracy Magnehelic® gauge delivers accuracy within 1% of full scale. HA version includes a mirrored scale overlay and a six-point calibration certificate at no additional cost.

The Dwyer 2000 Magnehelic Differential Pressure Gauge is an IP67 rated highly reliable and robust instrument for measuring air and non-combustible gases. Easy-to-read gauge for clear visibility from a distance. Features:

  • No power required
  • Patented design provides quick response to pressure changes
  • Durable housing and high-quality components ensure long service life
  • High accuracy option delivers double the precision of the standard Magnehelic® gauge
  • Operating pressure up to 35 psig and includes an overpressure relief plug that opens at approximately 25 psig
  • Accessories include two 1/8″ NPT plugs, two 1/8″ pipe thread to rubber tubing adapters, and three flush mounting adapters with screws

Typical Applications

  • Filter monitoring
  • Air velocity using a Dwyer pitot tube
  • Blower vacuum monitoring
  • Fan pressure indication
  • Duct, room, or building pressure monitoring
  • Cleanroom positive pressure indication
