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. An additional HOBO water level logger (4m type) is used to acquire atmospheric pressure for further data correction, allowing for more precise data (when conducting multiple water level observations within the same area, one atmospheric pressure correction logger can be used for all acquired water level loggers). No vent pipe is required, freeing users from various issues related to pipe installation (installation work, maintenance, accuracy errors). The completely sealed housing structure ensures long-term trouble-free and maintenance-free operation. An optical USB interface is adopted for data retrieval, reducing communication troubles during data collection. Lightning protection structure - no signal wire is needed, with a shielded structure for the electronics inside the housing. Robust ceramic pressure sensor. Comes with NIST-compliant accuracy calibration certificate (15, 21, 29 psia, 3 points). Patent number (U.S. Patent) 6,826,664.
basic information
The HOBO Water Level Logger (water level logger) is a highly accurate and easy-to-operate water level logger that offers exceptional cost-effectiveness. It can record water level measurements and temperature changes over long periods in wells, rivers, lakes, dams, reservoirs, estuaries, and the sea (*). The sensor, memory, and battery are integrated into a single structure, eliminating the need for troublesome maintenance such as installing vent tubes or replacing desiccants. Depending on your application, you can choose from four measurement range types: 4m, 9m, 30m, and 76m. * Please select the seawater-compatible model when used in seawater/brackish water. 【Requirements for operation】 - Dedicated software HOBOware Pro (BHW-PRO-USB) - Optic USB base station (BASE-U-4)
