Temperature conversion:
Temperature conversion refers to converting the current measured pH value to the value when the temperature is 25℃. (Assuming that all other things are constant and only the temperature changes, the pH value required by many standards generally refers to the pH value at 25°C. As we said above, the pH value measured by our pH meter is the pH value at the current temperature, which will be deviated from the pH value at 25°C. The temperature coefficients of different solutions also differ greatly. Pure water is about 0.015pH/C, and the temperature coefficient of trace (mg/L grade) contaminated pure water rises to about 0.033pH/C. So in strict cases, you have to convert 25°C.
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.
