Dwyer 2000 Series [2220] Magnehelic Pressure Gauge, 0 to 20 psi. Dwyer 2000 series pressure gauge uses Dwyer's simple, frictionless Magnehelic® gauge movement, to quickly indicate low air or non-corrosive gas pressures — either positive, negative (vacuum) or differential. The design resists shock, vibration and over-pressures. There is no manometer fluid to evaporate, freeze or cause toxic or leveling problems. It's inexpensive, too.
The Dwyer 2000 series is available in ranges up to 30 psi (or equivalent) and is accurate up to ±2% of FS. The gauge is available in a number of pressure units, including dual scale. Compound ranges are also available. A number of options can be added to tailor the 2000 series gauge to your specifications.
The Dwyer 2000 series pressure gauge has a 4-inch dial face. It can be either flush or surface mounted with standard hardware supplied. Although calibrated for vertical position, many ranges may be used at any angle by simply rezeroing. However, for maximum accuracy, they must be calibrated in the same position in which they are used.
