Description
Maximum accuracy
HOBO® U20L Water Level records water level and temperature with high accuracy and reliability. The datalogger uses a ceramic pressure sensor to measure level, thus ensuring its durability and avoiding accuracy drifts over time.
The free HOBOware® software, available for Windows and Mac, allows downloading and viewing the recorded data, in addition to configuring all the instrument parameters, such as date and time. The communication with the computer is done either through the BASE-U-4 universal optic USB base station or using the U-DTW-1 shuttle (none included).
Compact and waterproof design
The datalogger features a compact design and is entirely made of corrosion resistant materials to ensure high resistance in water. The included lithium battery guarantees a long life before having to be replaced.
