Description
The Onset U20L-02 HOBO Water Level Data Logger, 100 ft. is a 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.
Note: U20L-02 requires the HOBOware software (free to download) to operate, and either a U-DTW-1 Waterproof Shuttle or the Base-U-4 Optic USB Base Station for configuration and data offload. Please also note that a USB interface cable comes with the purchase of a HOBOware Pro CD (BHW-PRO-CD), only.
