Series 2000 Magnehelic® Differential Pressure Gages
Indicate Positive, Negative or Differential, Accurate within 1%
No Power Required
Low Cost
Used in Isolation/ Hospital Environments and Temporary Units (no power required)
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, located below in the Product Configurator. Also included with the –HA option at no extra cost are a mirrored scale overlay and a 6 point calibration certificate.

NIST CALIBRATION available in Product Configurator.

Note: May be used with Hydrogen. Order a Buna-N diaphragm. Pressures must be less than 35 psi.

Please see Series AT-2000 for ATEX approved.
