Product Code: U20L-01 The HOBO U20L-01 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% measurement 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 HOBO Waterproof Shuttle or the Universal Optic USB Base Station for configuration and data offload, HOBOware software (free download). NOTE: HOBOware Pro is required when using the U-DTW-1 Waterproof Shuttle. Highlighted FeaturesSelf-contained non-vented design enables easy deployment 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 30 feet 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 This data logger operates in outdoor and underwater environments.
