Technical Support

Support 1-2 point automatic calibration. Two point calibration steps: ① Preheat the machine, wash the electrodes, and immerse them in the first buffer solution (such as 6.86pH); ② After the reading stabilizes, press “confirm” to complete the first point calibration; ③ Wash the electrode and immerse it in a second buffer solution (such as 4.00pH or 9.18pH). After stabilization, press “confirm” and the instrument will automatically end calibration and return to measurement mode.

There are a few possible explanations for this phenomenon: a low ion concentration in the solution (such pure water), a low temperature, or electrode contamination. Recommendation: Make sure that the waiting period for the measurement is extended; ensure that the temperature compensation is accurately calibrated; ensure that the electrode is cleaned and activated; The use of a pure water electrode is permitted in the event that the sample in question is pure water.

It is highly likely that the electrode bubbles are contaminated or passivated. First, rinse with distilled water, and then choose a cleaning agent based on the type of pollutant (such as dilute acid for inorganic dirt). After cleaning, soak in the electrode replenishment solution for 2-4 hours to activate. If there is still no improvement, the electrode needs to be replaced.
