Dwyer Differential Megnehelic Pressure Gauge

Series 2000 Magnehelic® Differential Pressure Gages.
Series 2000 Magnehelic® Gage uses 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.
Note: May be used with Hydrogen. Order a Buna-N diaphragm. Pressures must be less than 35 psi.
