Operation steps and application of pen conductivity meter

Pen conductance operation steps

    1. Remove the protective case.

    2. Touch the "ON/OFF" switch.

    3. Insert the conductivity meter into the solution to be measured until the liquid is submerged just below the "immersion line".

    4. Shake the instrument gently, and read after the displayed value is stable.

    5. After use, press "ON/OFF", turn off the power, clean the electrode with distilled water or alcohol, and put on the protective cover.

Battery installation:

    If the display is blurred or not displayed, and the error of the displayed value is large, the battery should be replaced in time. When replacing the battery, pull out the battery to replace it. Pay attention to the polarity of the battery and the direction of the battery compartment, and do not deform the battery contact piece.

Pen conductance application

    1. After the pure water and mineral water have been placed for a long time, the conductivity value will rise too high compared with the beginning, and the comorbidity du and the total number of bacterial colonies will also increase accordingly. At this time, it is not allowed to drink raw, which will affect health;

    2. The conductivity value of pure alcohol is 0, if it is greater than 0, it means impure;

    3. The conductivity of the aqueous solution is directly proportional to the amount of dissolved solids, so the smaller the indicated value, the smaller the impurities in the water;

    4. Users above the 3rd floor are supplied with water from the water storage tank on the top floor, which is likely to cause secondary pollution. The change of the conductivity value should be checked frequently, and the property management department can be urged to clean it regularly.

    5. How much washing powder should be put in the washing machine, and the experience can be digitized by testing with a conductivity meter. After the cleaning procedure, the indication value detected before draining is the same as the tap water, which can be regarded as clean. If the indication value exceeds the tap water, the amount of washing powder input should be reduced;

    6. If the fruits and vegetables are soaked in water, if the measured conductivity value is too high, chemical pollution may be suspected and attention should be paid.

    7. In the process of swimming in the swimming pool, the change of the cleanliness of the pool water can be measured. If the value is too high, attention should be paid to it;

    8. If the indication value of deep well water is as high as 300 or more, it means that the impurity content is too high;

    9. Each region and city has different conductivity values ​​due to different pipelines and water sources;

    10. The hard water in the north contains calcium and magnesium ions, and the conductivity value is too high, which will cause Graduation; generally hard water is 150~400 (Graduation). Ultra-hard water (if salt water) is greater than 400 (severe Graduation) (limited to the detection of water before treatment).

    11. After the flower fertilizer is prepared according to the regulations for the first time, measure its value, and use this number to facilitate future preparation;

    12. The water used in goldfish tanks can be measured to know its cleanliness. If the value is long and big, the water should be changed in time;

    13. The value of water for mariculture can be measured for future preparation and testing.

Notes on pen conductance:

1. When measuring, shake the instrument gently a few times to avoid air bubbles on the electrode, otherwise it will affect the measurement results

2. Do not adjust the instrument at will, only when the instrument has been used for a long time, or is used very frequently, it should be recalibrated

3. If there is a large error in the displayed value, the displayed value jumps, or the displayed value does not return to zero, etc., insert the part below the immersion line of the instrument into alcohol and shake it a few times to clean the sensor. In low temperature or humid state, the indication value does not return to zero (the last digit of the display screen is within 2), and the measured value will not be affected.
