  • No weights to load and unload, transport or send out for calibration
  • Provides real-time pressure indication with no need to know and correct for local gravity or ambient temperature
  • No piston-cylinder changes
  • No significant sensitivity to level or vibration
  • Able to set and read any pressure value exactly, no minimum increment limited by smallest available masses; perfect for applications that require setting a nominal pressure precisely on the device under test and measuring it, such as analog gauge calibration
  • Operates in any unit of measure, switching easily from one unit to the next
