SD325 Con

The SD335 Conductivity Handheld Meter is a rugged and reliable solution for measuring conductivity, total dissolved solids (TDS), salinity and temperature in demanding field environments. Designed for professional water quality monitoring, it combines accurate measurement technology with a durable IP67 waterproof housing, making it ideal for reliable on-site analysis.

With advanced features including automatic temperature compensation, integrated data logging and Good Laboratory Practice (GLP) functions, the SD335 provides accurate and traceable measurement results. Its robust construction and user-friendly operation make it suitable for applications across industrial water systems, water treatment, environmental monitoring and process control.


The large backlit LCD display ensures measurement results are clearly visible in all conditions, while the protective housing provides a secure grip and protection against accidental drops. The integrated rear stand can also be used as a hanger or belt clip, providing additional flexibility when working in the field.


The SD335 supports efficient data management through its integrated logger, allowing users to store measurement results and transfer data to a computer via USB connection. With both manual and automatic logging options available, it provides a practical solution for recording and managing water quality measurements over time.


Depending on the required measuring range, the SD335 can be equipped with different conductivity measuring cells featuring advanced 2-pole or 4-pole technology, providing flexibility for a wide range of applications.
