How to use ph meter digital in china

ph meter digital in china is also called acidity meter. It is often used to measure and detect the acidity and alkalinity of liquid media. It is widely used in industry, agriculture and environmental protection. If the measured data is inaccurate, it will cause serious consequences for engineering or the environment. Therefore, the correct use of ph meter digital in china is particularly important, and it is necessary to strictly follow the correct method and sequence in order to obtain more accurate measurement data. Then let's take a look at how to use ph meter digital in china according to the correct steps:

1. Remove the composite electrode cover before starting the machine;

2. Rinse the electrode with distilled water, absorb the water with filter paper, be careful not to break the glass electrode at this time;

3. Turn on the power, you need to preheat for 5-30 minutes according to the length of the measurement time;

4. Before entering the calibration step, first unplug the power plug and connect the composite electrode;

5. Adjust the switch knob to the pH level;

6. Adjust the white line of the temperature compensation knob to the solution temperature value;

7. Turn the slope adjustment knob clockwise to the limit;

8. Insert the previously cleaned electrode into the pH buffer.
