The HOBO U20L-02 is a low-cost, research-grade water level data logger for continuously measuring water level and temperature in a wide range of underwater environments. It features 0.1% accuracy, a polypropylene housing for use in both fresh and salt water, and a non-vented design for convenient and hassle-free deployment.

This data logger requires either the U-DTW-1 Waterproof Shuttle or the Base-U-4 Base Station for configuration and data offload, HOBOware software (free download). NOTE: HOBOware Pro is required when using the U-DTW-1 Waterproof Shuttle. See compatible items.

Self-contained non-vented design enables easy deployment
Ideal for use in both fresh and saltwater environments, including wells, streams, lakes, wetlands, and tidal areas
Depths up to 100 feet (0-30,6 m)
Durable ceramic pressure sensor withstands freezing
HOBOware Pro software provides easy conversion to accurate water level reading, fully compensated for barometric pressure, temperature, and water density
