HOBO Water Level (13 Feet) Data Logger
Product Code: U20L-04
The HOBO U20L-04 Water Level Data Logger is a compact, rugged data logger designed for long-term monitoring of water level and temperature in freshwater environments. The logger uses a vented pressure sensor to measure water pressure while automatically compensating for changes in atmospheric pressure.
The U20L-04 is suitable for groundwater monitoring, stream and lake studies, hydrology, watershed research, environmental monitoring and water-resource management. Its compact design allows it to be installed in monitoring wells, stilling wells and other confined locations.
The U20L-04 has a 0–4.4 m (0–14.7 ft) water-level measurement range, with a 0.05% FS accuracy. It can record measurements at user-selectable intervals and stores up to 21,200 measurements.
The logger features a durable, corrosion-resistant housing and is designed for extended deployment in freshwater applications.
