• No on-site calibration required
• Performs extremely accurate measurements:
  • linear deviation is less than 0.02%
  • resolution is 1 part in 250,000
  • accuracy over temperature range exceeds ±　0.01 ft. of water
• Enclosure is nonconductive and corrosion proof
• Output options: SDI-12 and RS-232
• Pressure measurement data is transmitted digitally over long cable lengths without error
• Sensor cable has large venting capacity for compensation of rapid barometric pressure changes
• Dry air moisture barrier system provides atmospheric compensation without impairing the sensor's accuracy
• Simple to install, use, and maintain
