The Dwyer 490A Digital Manometer is a versatile, hand-held, battery operated manometers available in several basic ranges for positive or positive differential pressure measurement and can tolerate most liquid media compatible with 316LSS. A new feature added to the Series 490A is a field adjustable damping, which allows the user to choose the level of display averaging rate corresponding to the fluctuation level common in many applications.

Dwyer 490A Digital Manometer Applications Include

  • Chiller to coils for freeze protection
  • HEPA filters to determine when a filter needs to be changed
  • Measure pressure drop across pumps
  • Valves to determine valve position
