Probe Setting

Perform sensor calibration and view of sensor status.

After the probe is connected to the controller, it needs to be calibrated first due to the error between

the signal of the actual electrode and the standard.

pH Calibration

1. Preparation before calibration

In the menu “ select probe ”, select “ pH Glass probe ” or “ pH Antimony probe ”
pH 4.01, 6.86, 9.18 standard solution (1)
Deionized cleaning solution and absorbent paper

2. Zero Calibration

(1) Clean the probe with deionized cleaning solution, dry it with absorbent paper and put it

into pH 6.86 standard solution;

(2) After the measured value is stable, select “ 6.86pH CAL ” to start calibration;

3. Acid slope Calibration

(1) Clean the probe with deionized cleaning solution, dry it with absorbent paper and put it

into pH 4.01 standard solution;

(2) After the measured value is stable, select “ 4.01pH CAL ” to start calibration;

4. Alkali slope Calibration

(1) Clean the probe with deionized cleaning solution, dry it with absorbent paper and put it

into pH 9.18 standard solution;

(2) After the measured value is stable, select “ 9.18pH CAL ” to start calibration;

ORP Calibration

1. Preparation before calibration

In the menu “ select probe ”, select “ ORP probe ”
ORP 86mV, 256mV standard solution (1)
Deionized cleaning solution and absorbent paper

2. Zero Calibration

(1) Clean the probe with deionized cleaning solution, dry it with absorbent paper and put it

into ORP 86mV standard solution ;

(2) After the measured value is stable, select " 86mV CAL " to start calibration;

3. Slope Calibration

(1) Clean the probe with deionized cleaning solution, dry it with absorbent paper and put it

into ORP 256mV standard solution;

(2) After the measured value is stable, select " 256mV CAL " to start calibration;

pH ORP controller Applications:

Acid and base (pH) regulation is to stabilize the PH value of the process medium in the required range to meet the needs of the process, in the electroplating process of electroplating bath pH control, metallurgical flotation process of pulp PH control, chemical process of the process medium mother liquor pH control. In the water treatment process, the pH value of the treated water will greatly affect the use effect of various chemicals, and different kinds of wastewater may not be allowed to discharge in the pH range after the completion of various treatments.
