Series 2000-HA High Accuracy Magnehelic® Differential Pressure Gage - Dwyer
The Series 2000-HA High Accuracy Magnehelic® Gage is twice as accurate as the standard Magnehelic® gage. The well-engineered High Accuracy Magnehelic® Gage offers a mirrored overlay as standard in order to eliminate any parallax error when taking measurements. A six point calibration certificate is included with each high accuracy model. The rugged IP67 casing helps fully protect against dust and water ingress. The redesigned corrosion resistant brushed 304 stainless steel bezel option offers a clean tapered design, yet minimizes the possibility of any dust accumulation on the edges. *See Series 2000 Magnehelic® Gage for additional information.

Questions
- Question
- I have a Magnehelic gage 2000-00N I purchased for a clean room. Should the installers set the "set" screw to get the gage back to (0) or will that mess up the calibration?
- Answer
- After the Magnehelic has been installed, disconnect pressure lines to vent both sides of the gage to the atmosphere and re-zero. This will not mess up the calibration. This should be done occasionally.
