Now, four No.5 batteries are installed in the battery box at the bottom, electrolyte solutions with a certain proportion (or medium) are injected into the solution boxes, the electrode covers are covered, and then they are connected to the input ends of the display panel with wires, so that the lighting of the indicator light can be seen. If the indicator light are all on, it means that the conductivity of the solution is strong; If the indicator light is not fully lit, it means that the conductivity of the solution is weak, thus indicating that the conductivity of electrolytes with different proportions (or media) is different. The instrument is equipped with fine adjustments to achieve satisfactory results.
