Products Description
PH value automatic controller/automatic control system/automatic control device refers to a set of devices that automatically and accurately regulate the PH value (acidity and alkalinity) of the measured liquid. By setting the control range of the PH value to be controlled, the WK controller will automatically control the discharge of acid or alkali, so that the PH value of the measured liquid can be stabilized within a certain range, and it is fully automatically controlled.
