• For installation in pipes
• For use in ultra-pure water applications
• For trace measurement
The measurement of conductivity is generally expressed in S/cm (or mS/cm) which is the product of the conductance of the test solution and the geometric factor of the measuring cell. The scale for aqueous solutions starts at a conductivity of 0.05 µS/cm (at 25 °C) for ultra-pure water. The conductivity of natural waters, such as drinking water or surface water is typically in range of 100 – 1000 µS/cm. The upper End of the scale is reached by some acids and alkalis.
