S&DL Water Level and Conductivity Meter

S&DL (Sensor and Data Logger) Water Level and Conductivity Meter measures water level, conductivity and water temperature at a same time. These sensor and data logger is combined into one (1) probe, then stable data can be recorded easily.

Electromagnetic induction type is applied for the conductivity measurement, and it leads to stable monitoring in the long-term.

Retrieving data and monitoring setting are easily carried out using a laptop computer with S&DL Assist (software) at the site.

User can expand this stand-alone monitoring system to remote monitoring system using GSM i-SENSOR data transfer unit smoothly / reasonably.

On the investigation of aqueous environment, such as survey on groundwater salination, water contamination study and so on, water level and conductivity data are required. This instrument can obtain the both data at a same time by the probe. Hence, its installation and maintenance work is easier and more efficient.

Features

  • 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.
