I. pH Buffers The temperature coefficient of pH calibration buffers 1.68, 4.00, 4.01, 6.86, 7.00, 9.18 , 10.01 and 12.46 pH are stored inside the instrument. The buffers used to calibrate the instrument must exhibit the same temperature characteristics as the stored values. - Page 18 Standard solution of 111.9 mS/cm at 25 ℃: Accurately weight out 74.264 grams of research grade dried Potassium Chloride (KCL). Dissolve in 1000 ml of distilled water. You can store the unused portion of the standard [Note: solution in a plastic container for six months but the air space between the cap and the solution must be kept to an absolute minimum.
