The WaterLOG® Model H-310 is a submersible pressure transducer for water level monitoring. Accuracy exceeds government requirements of ±0.01 ft. This user-friendly model is simple to install and maintain with no on-site calibration required.

KEY FEATURES

  • Performs extremely accurate measurements
  • Enclosure is non-conductive and corrosion proof
  • Linear deviation is less than 0.02%
  • Resolution is 1 part in 250,000
  • Output options: SDI-12 and RS-232
  • Pressure measurement data is transmitted digitally over long cable lengths
  • 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
