DTK CD 4307SD

The DTK CD4307SD is a versatile multi-purpose water quality meter designed for accurate measurement of conductivity, total dissolved solids (TDS), salinity and temperature. Combining reliable measurement performance with advanced data logging capability, it provides a practical solution for professionals carrying out routine water quality monitoring.

Designed for ease of use, the CD4307SD allows users to quickly switch between measurement parameters using the dedicated function button, while the display provides clear visibility of the selected reading alongside temperature information. Automatic temperature compensation ensures reliable conductivity measurements across changing conditions.


The meter features a long-life carbon rod conductivity electrode, providing durability and consistent performance over extended periods of use. With real-time SD card data logging, users can easily record, store and transfer measurement results without the need for additional software.


Built for both field and laboratory environments, the CD4307SD includes a large backlit LCD display, fold-out stand and tripod connection for convenient operation. Additional functions including auto power off, hold, and min/max readings provide improved usability during routine testing.


Each meter is supplied with a conductivity probe, 6 x AA batteries and a certificate of conformity valid for 12 months. Calibration services are also available through DTK Water to support ongoing measurement accuracy.
