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.
Inquire About This Product
basic information
The HOBO Water Level Logger (water level logger) is a highly cost-effective water level logger that offers high precision and ease of operation. It can record water level measurements and temperature changes over long periods in wells, rivers, lakes, dams, reservoirs, estuaries, and the sea, among others. Since the sensor, memory, and battery are integrated, there is no need for troublesome maintenance such as installing vent tubes or replacing desiccants. Depending on the application, you can choose from three measurement range types: 9m, 30m, and 76m. (Note) Please select the seawater-compatible model when using it in seawater (saltwater). 【Required for operation】 - Dedicated software HOBOware Pro (BHW-PRO-USB) - Optic USB base station (BASE-U-4)
