- pH, water level and water temperature are measured by a setting time interval.
- KCI non-refill type pH glass electrode is applied. It is not necessary to refill an inner solution and a little maintenance is required.
- A special construction work and/or equipment are not needed, and user just set the battery case at the top of a monitoring well/hole.
- It makes possible to have superior stability by putting data logger in the water where temperature rarely change. Because of applying the unified probe consisted by the sensor and data logger, it is not affected by exogenous noise.
