Using the simple, frictionless Magnehelic movement which transmits the effect of changes in pressure from a diaphragm to an indicating pointer by means of magnetic linkages, they quickly indicate low air and compatible, non-corrosive gas pressures, either positive, negative (vacuum) or differential. The design resists shock, vibration and over-pressures. It avoids wear and physical contact which might destroy the accuracy and sensitivity of the instrument. There is no manometer fluid to evaporate, freeze or cause toxic or levelling problems.
