    Product description

    The HOBO water level data logger features high accuracy at a great price and ease-of-use, with no cumbersome vent tubes or desiccants to maintain. This data logger is ideal for recording water levels and temperatures in shallow wells, streams, lakes and freshwater wetlands.

    Highlighted Features

    • Lightning protection - no long signal wires, and electronics are shielded in stainless steel housing for use in freshwater (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
