And the pH meter uses the three-point calibration method to calibrate the electrode to the solution of pH 4.00, pH 6.86, and pH 9.18 to ensure the accuracy of measurement. ORP and H2 meters are pre-calibrated.pH Meter with Automatic Temperature Compensation: Temperature will affect the reading level, and automatic temperature compensation can ensure that you get the best reading. compared with other pH meters for water, there is only a range of 0°C-50°C. our digital pH meter has a better range of
