Portable Magnahelic® Pressure-Air Velocity Gages
Dead read-out no tapping necessary
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 scale. †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.
Portable Magnehelic Unit includes:
