The datalogger GEALOG micro is especially suited for all applications requiring high reliable registration of water level and water temperature made under very harsh environmental conditions. It is installed into ground water pipes with diameters from 2 inch onward. The water level is measured by a high precision pressure sensor, the water temperature by an integrated temperature sensor. Atmospheric air pressure variations are compensated by a capillary tube inside the sensor cable.The complete data logger electronics is installed in the submersible, watertight housing.
The GEALOG micro is powered by internal batteries, which guarantee the operation up to 10 years (depending on measuring rate) without changing batteries. Batteries can be factory-replaced. For configuration and data-readout the software-tool “Gealog for Windows” is used. The GEALOG micro can be easily fixed into groundwater pipes by optionally supplied mounting units .
