Use with Pitot tube for air velocity
measurement or without for pressure measurement. Easy and quick
to use, Portable Magnehelic® Gages with dual scale are less
sensitive to level than liquid gages, yet offer accuracy to ±2%
over the full scale¹. Air Velocity Scale provides direct
reading for standard air without conversions. They are handy
to use on a ladder or in confined locations encountered in field
testing. Dwyer magnetic linkage provides exceptionally responsive,
consistently accurate indication of air velocity, positive, negative
or differential pressures in air and non-corrosive gases. Pointer
movement is inertia-free and drift-free. Highly resistant to
shock and vibration.
