Page 10: Ph Buffer Temperature Dependence
pH BUFFER TEMPERATURE DEPENDENCE ACCESSORIES Temperature has an effect on pH. The calibration buffer pH CALIBRATION SOLUTIONS solutions are affected by temperature changes to a lesser HI 70004P pH 4.01 buffer solution, 20 mL sachet, 25 pcs degree than normal solutions. HI 70007P pH 7.01 buffer solution, 20 mL sachet, 25 pcs For manual temperature calibration please refer to the following chart. - Page 11 TEMPERATURE CORRELATION FOR pH ELECTRODE CONDITIONING SENSITIVE GLASS AND MAINTENANCE The resistance of glass electrodes partially depends on the temperature. Note: To prevent damage to the electrode, remove the pH The lower the temperature, the higher the resistance. It takes longer time electrode from the solution before turning the meter off.
