13-Foot Depth Titanium Water Level Data Logger - HOBO - U20-001-04-Ti
Providing a range of narrow measurements for best accuracy, this version is ideal for monitoring water levels and temperatures in wells, rivers, lakes and wetlands.
Like other HOBO water level counters, the 13-foot version offers exceptional value and ease of use, with no ventilation or desiccant tubes that are not practical to maintain. These data loggers are ideal for recording water levels and temperatures in salt water environments.
In which environment does this data logger operate?
This data logger operates in outdoor and underwater environments.
What measurements does this data logger do?
Data logger U20-001-04-Ti supports the following measurements: Absolute Pressure, Barometric Pressure, Temperature and Water Level
Feature
