Water Level Logger Hobo U20 Water Level Logger

High-precision water level logger

Using the dedicated software HOBOware, high-accuracy water level data is obtained by correcting the measured pressure with information such as atmospheric pressure, temperature, and fluid density. For atmospheric pressure correction, another HOBO water level logger (9m type) is used to obtain atmospheric pressure, further improving data accuracy (when conducting multiple water level observations in the same area, one atmospheric pressure correction logger can be used for all obtained water level loggers). No vent pipe required - liberation from various issues related to pipe installation (installation work, maintenance, accuracy errors). Completely sealed housing structure for long-term trouble-free and maintenance-free operation. Adopts an optical USB interface for data retrieval, reducing communication troubles during data collection. Lightning protection structure - no signal wire required, with a shielded structure for the electronics inside the housing. Robust ceramic pressure sensor. Includes NIST-compliant accuracy calibration certificate (15, 21, 29 psia, 3 points). Patent number (U.S. Patent) 6,826,664.
