Here are some standard solutions the user can prepare to calibrate the probe of the model EC3840. Standard solution of 1413uS at 25℃: Accurately weight out 0.746 grams of research grade dried Potassium Chloride (KCL). -
Page 7: Calibration
Standard solution of 111.9mS at 25℃: Accurately weight out 74.264 grams of research grade dried Potassium Chloride (KCL). Dissolve in 1000ml of distilled water. You can store the remaining solution in a plastic [Note: container for one week but the air space between the cap and the solution must be kept to an absolute minimum. -

Note: Be certain to press “Enter” key to reset the cell constant to 0.50. If “Mode” key is pressed, the unit retains the previous cell constant and calibrates from a value that is already offset. Temperature Coefficient The unit uses the temperature coefficient to calculate temperature compensated conductivity. -
