- Electrode type of the conductivity measurement is adversely affected by dirt on the electrode and polarization capacity. To avoid such demerits, this instrument applies the electromagnetic induction type.
- 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
