Description

Select the 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. No manometer fluid to evaporate, freeze or cause toxic or leveling problems.

The Magnehelic is the industry standard to measure:

  • fan and blower pressures
  • filter resistance
  • air velocity
  • furnace draft
  • pressure drop across orifice plates
  • liquid levels with bubbler systems
  • pressures in fluid amplifier or fluidic systems

The Magnehelic also checks gas-air ratio controls and automatic valves, and monitors blood and respiratory pressures in medical care equipment.
