12.41ppt conductivity/TDS calibration solution in a choice of 500 or 230ml bottle sizes.

1413uS/cm conductivity calibration solution is the most commonly used calibration solution for conductivity meters.

Conductivity Solution 5 000uS in 500ml or 230ml bottles.

12,880uS/cm conductivity calibration solution.

80,000uS conductivity calibration solution.

111,800uS conductivity solution in 230ml or 500ml bottle sizes.

Hanna 80000 µS/cm calibration solution is needed for the proper calibration of instrumentation used to measure high conductivity samples, such as very dirty wastewater, solutions with suspended materials and plating baths.

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

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.
