Conductivity Calibration Solution 12.88mS/cm (500ml)


500ml of 12.88mS/cm Conductivity Standard.

SKU: A3056 Category:

EDT directION manufacture a range of conductivity standard solutions. This enables the successful and accurate calibration of our conductivity meters and electrodes.

The measurement of conductivity requires that the sample be aqueous and to be of adequate volume to cover the electrode surfaces. If the samples and standards are not of the same temperature it is important that temperature compensation is applied.

Conductivity increases approximately 2% per degree centigrade. Normally the conductivity calibration is carried out on one point. One useful check is that the conductivity in air should be zero as there is no conductive material between the electrodes.

EDT directION conductivity standards are Potassium Chloride solutions in either 100ml or 500ml sealed plastic bottles. For correct use the appropriate volume of standard should be poured into a clean beaker or container. Do not calibrate by placing the conductivity cell in the bottle as this will contaminate the solution. Following calibration remember to close the bottle to avoid evaporation or contamination and do not pour the used standard back into the bottle.

EDT directION also produce a 1413µS/cm conductivity standard solution. This is available in both 100ml and 500ml quantities.
