Monitor water levels and temperatures in wells, streams, lakes and wetlands (freshwater) with HOBO U20 Stainless Steel Water Level Data Loggers. HOBO U20 loggers offers a great value and easy deployment since there are no cumbersome vent tubes or desiccants to maintain. For saltwater deployments, such as brackish wetlands and tidal areas, choose HOBO U20 Water Level Titanium.

Highlighted Features

  • Lightning protection - no long signal wires, and electronics are shielded in housing. 
  • HOBOware Pro software provides easy conversion to accurate water level reading, fully compensated for barometric pressure (see demo) temperature, and water density.
  • Multiple-rate sampling (see demo) allows faster sampling at critical times such as when pumping starts or stops.
  • Available in 4 depth ranges
  • Ideal for use in wells, streams, lakes, wetlands and tidal areas
  • No-vent-tube design for easy reliable deployment
  • Available in stainless and titanium versions
  • Durable ceramic pressure sensor
  • 3-point NIST-traceable calibration certificate included
