This conductivity solution at 84 µS/cm makes it possible to calibrate instruments with a conductivity scale of up to 200 µS/cm as used, for example, in the measurement of pure or distilled water.

The 1413 µS/cm solution is the one best suited for general use. This solution is also available in combination kits with the pH 7 buffer for the easy calibration of multiparameter instruments. It is also available in different sized bottles and in si

This solution is ideal for those applications that need to achieve higher reading accuracies in a conductivity scale between 2000 µS/cm and 10000 µS/cm.

Hanna has created a 5000 µS/cm calibration solution in a wide range of sizes and p

The 12880 µS/cm calibration solution is widely used to assure the proper performance of conductivity meters with a scale higher than 10 mS.cm.

This calibration solution is useful to calibrate instrumentation used to measure samples with conductivity higher than 100 mS/cm.
