DWYER MAGNEHELIC Differential Pressure Gauges 81 Model Number

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 Dwyers 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.
