HOBO 100-Foot Depth Water Level Data Logger(U20-001-02-Ti)

HOBO 100-Foot Depth Water Level Data Logger(U20-001-02-Ti)

Overview

The HOBO Water Level Titanium is recommended for saltwater deployment for recording water levels and temperatures in wetlands and tidal areas. This data logger features high accuracy at a great price and HOBO ease-of-use, with no cumbersome vent tubes or desiccants to maintain.

Highlighted Features

  • Lightning protection – no long signal wires, and electronics are shielded in a titanium housing for use in saltwater (see the Water Level logger sensor location drawing)
  • 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
