Magnehelic™ Manometers by Dwyer

Description:

Select the Magnehelic® gage for high accuracy (guaranteed within 2% of full scale)  to suit your radon mitigation needs precisely. Using Dwyer's simple, frictionless Magnehelic® gage movement, it quickly indicates low air either positive, negative (vacuum) or differential. The design resists shock, vibration and over-pressures. No manometer fluid to evaporate, freeze or cause toxic or leveling problems. It's inexpensive, too.
