1. Overview of D pen
It is the abbreviation of English d and its Chinese translation is the total amount of dissolved solids. The measurement unit is mg/L ( / ) It indicates how many milligrams of solid impurities are dissolved in liters of water.
In layman terms, the value represents the content of dissolved impurities in water. The larger the value, the greater the content of impurities in the water, and the conversely, the smaller the content of impurities in the water.

2. Factors affecting the D pen test
The optimal test temperature of the water temperature pen is ℃ and cannot be used to measure high-temperature water (for example: hot boiling water)
The water flow velocity pen cannot be used to measure water bodies with large shaking
The water pollution pen cannot be used to measure water bodies with high pollution concentrations
3. How to use the D pen
Take down the D pen Pen
Open the switch of the pen case
Place the D pen
into the test solution. The height of the solution should not exceed
Stir the D pen
in the solution until the reading stabilizes (- seconds) The D value will be displayed on the screen. To lock the value, press the D key.
After use, dry the water on the pen tip and cover the D pen cover back.
Precautions for use: Avoid immersing the D pen in water, avoid direct light and high temperatures, and avoid impact, stress and falling.
4. Common knowledge about D pen application
After pure water and mineral water have been left for a long time, the D value will rise too high compared to the beginning. The total number of viruses and bacterial colonies will also increase accordingly. At this time, drinking raw water will not affect your health
, If the D value of pure alcohol is greater than 1, it means it is impure
, D is the total dissolved solid content. If the value shown is milligrams of impurities per liter, users above the building are likely to receive water from the top-floor water tank, causing secondary pollution. Changes in the D value should be regularly detected to urge the property management department to clean regularly.
、 How much washing powder should be put in the washing machine can be measured with D pen to digitize the experience. After the cleaning process and before draining, if the indication value is the same as that of tap water, it can be regarded as clean. If the indication value exceeds that of tap water, the amount of washing powder should be reduced
. If fruits and vegetables are soaked in water, the D value will be measured if it is too high. Suspected or suspected chemical contamination should be taken seriously.
, When swimming in the swimming pool, the measurable changes in the cleanliness of the pool water should be taken seriously. If the indication value is too high, attention should be paid
. If the indication value of deep well water is higher than above, it means that the impurity content is too high
, Every regional city Due to different pipes and water sources, the D value is different
. The hard water in the north contains calcium and magnesium ions with a high D value and will form scale. Generally, hard water ~ (scaling). Super hard water (if salt water) is greater than (severe scaling).
. After the flower fertilizer is prepared according to the regulations for the first time, measure its value. Use this number to facilitate future preparations
. Use the water in the goldfish tank to measure its value to know its cleanliness. If the value is too high, the water should be changed in time
. The value of mariculture water can be measured for future preparation and testing.
