elect the SERIES 2000 Magnehelic® Gage for high accuracy--guaranteed within 2% of full scale--and for the wide choice of 81 models available to suit your needs precisely. Using Dwyer's simple, frictionless Magnehelic® gage movement, it quickly indicates low air or non-corrosive gas pressures--either positive, negative (vacuum) or differential. The design resists shock, vibration and over-pressures.
Note: May be used with Hydrogen. Order a Buna-N diaphragm. Pressures must be less than 35 psi.
