Conductivity standards and solutions from EDT DirectION are a full range of control standards for your electrochemistry analysis requirements. Every conductivity measurement requires a calibration standard solution to ensure accuracy and precision.
One point calibration can be performed in Air however a further point is required using a known standard prepared from Analar Potassium Chloride. Once used the standard needs to be discarded as they are easily contaminated and increase in conductivity on evaporation.
