Brand: Dwyer

Additional information


Indicate Positive, Negative or Differential, Accurate within 1%

Select the SERIES 2000 Magnehelic® Gage for a versatile low differential pressure
gage with a wide choice of 81 models and 27 options to choose from. Using Dwyer’s
simple, frictionless Magnehelic® gage movement, it quickly indicates air or noncorrosive gas pressures–either positive, negative (vacuum) or differential. The design
resists shock, vibration, over-pressures and is weatherproof to IP67.
Select the –HA High Accuracy Magnehelic® gage option for an accuracy within 1%
of full scale. Also included with the –HA option at no extra cost are a mirrored scale
overlay and a 6 point calibration certificate.

• Easy to read gage through undistorted plastic face permits viewing from far away
• Patented design provides quick response to pressure changes means no delay in
assessing critical situations
• Durable and rugged housing and high-quality components combine to provide longservice life and minimized down-time
• High accuracy option is twice as accurate as the standard Magnehelic® gage

• Filter monitoring
• Air velocity with Dwyer pitot tube
• Blower vacuum monitoring
• Fan pressure indication
• Duct, room or building pressures
• Clean room positive pressure indication
