with three keys for temperature and quality pure water machine TDS value testing, mineral testing pen

TDS Pen Introduction:
TDS stands for Total Dissolved Solids in English, translated as Dissolved Total Solids in Chinese. It is measured in milligrams per liter (mg/L) and indicates the milligram amount of soluble solids present in one liter of water.
The concept of TDS is an imported product widely used in the water field in the United States and Taiwan. The measurement tool for TDS value is usually a TDS pen, and its measurement principle is actually to indirectly reflect the TDS value by measuring the conductivity of water. In physical terms, the more dissolved substances in water, the higher the TDS value of water, the better the conductivity of water, and the higher its conductivity value.
Simply put, TDS value represents the content of dissolved impurities in water. The higher the TDS value, the higher the impurity content in the water; conversely, the lower the impurity content.
Factors affecting TDS value testing:
Water temperature: TDS pen cannot be used to measure high temperature water bodies (such as hot water)
The flow rate of water: TDS pens cannot be used to measure water bodies with significant shaking
Product Instructions:
Remove the pen holder and turn on the ON switch;
Place the pen into the test solution, and the height of the solution should not exceed 2cm;
Stir the pen in the solution until the reading stabilizes (2-6 seconds), and the TDS value will be displayed on the screen. Press the HOLD key to lock the value.
After use, wipe off the water on the tip of the pen, clean it with purified water, and then cover the pen cover back.
Precautions for use: Avoid soaking the TDS pen entirely in water, avoid direct sunlight, stay away from high temperatures, and avoid impact, heavy pressure, and falling.
Product usage scope:
Check whether the water quality of tap water, purified water, and mineral water meets the national drinking water standards: tap water below 300PPM, pure water below 50PPM (national standard), and mineral water between 100-200PPM.
The specifications and parameters of the test pen are as follows:
The lightweight sleeve weighs 28 grams and is the smallest and lightest portable TDS instrument in the market today, measuring 14.2 cm in length, 2.3 cm in width, and 1.3 cm in thickness.
The measurement range is wide and can measure 1-9990PPM (display 999PPM or above, the value should be X10).
The application temperature ranges from 0-50 degrees Celsius and can be stored at minus 30 degrees Celsius.
LCD display window with large screen and waterproof design, convenient for viewing and durable
Long battery life: Two CR1620 3V batteries are used, which can be used for more than 3 years. The automatic shutdown function is not operated for 10 minutes, saving battery life.
A well-designed pen tip electrode can be directly inserted into the tested aqueous solution for measurement, and the pen holder can also be used as a container for the tested aqueous solution, which is extremely convenient.
Fast measurement: Thanks to the delicate bare sensing element, a measurement can be completed in 5 seconds.
● With an accuracy of 1%, the titanium alloy probe has high water measurement accuracy and is free from magnetic interference in water.
Automatic temperature compensation can automatically convert the displayed value to the displayed value at 25 degrees.
Common sense of application:
1. After being stored for a long time, the TDS value of purified water and mineral water increases too much compared to the beginning, and the total number of co viruses and bacteria will also increase accordingly. At this time, it is not advisable to drink raw water, as it affects health;
2. Pure alcohol TDS value is 0, greater than 0 indicates impurity;
3. TDS stands for Total Dissolved Solids. The displayed value is 100, which means there are 100 milligrams of impurities per liter;
4. For users on the third floor or above, the water from the top storage tank is prone to secondary pollution. Therefore, it is recommended to regularly monitor changes in TDS values and urge the property management department to clean regularly.
5. How much laundry detergent should be put in the washing machine? Using a TDS pen to detect can digitize the experience. After the cleaning process, if the reading detected before drainage is the same as that of tap water, it can be considered clean. If the reading exceeds tap water, the amount of laundry detergent should be reduced;
6. If fruits and vegetables are soaked in water and their TDS values are found to be high, chemical contamination may be suspected and should be taken seriously.
7. During the process of swimming in the pool, changes in the cleanliness of the pool water can be measured, and excessive readings should be taken seriously;
8. If the reading of deep well water is above 300, it indicates that the impurity content is too high;
9. Due to differences in pipelines and water sources, TDS values vary in each region and city;
10. Northern hard water contains calcium and magnesium ions, with a high TDS value, which can lead to scaling; Generally, hard water is 150-400 (scaling). Super hard water (if saltwater) greater than 400 (severe scaling).
11. After the first preparation of flower fertilizer according to regulations, measure its value, and use this number to facilitate future preparation;
12. The water used in the goldfish tank can be measured to determine its cleanliness level. If there is a significant blockage in the numerical value, water should be changed in a timely manner;
13. The water used for aquaculture can be measured for future preparation and testing.
Note: This product is also suitable for soilless cultivation and requires a conductivity meter to measure the ion content of nutrient solution. This product can be used for measuring the concentration of nutrient solutions. Subtract the values of the second measurement. The method is to first measure the TDS value of tap water, then add nutrient solution and measure its value. The value obtained by subtracting it twice is the evaluated value.
This pen can measure the hardness and purity of water:
If the TDS exceeds 40, it is not considered pure water,
Generally, the well water in rural areas is above 40,
RO reverse osmosis, five stage filtration, without soft water function,
The TDS value is generally less than 35, and if it has a soft water function, the value should be even smaller.
The TDS value of distilled water is generally close to 0
The TDS value of purified water is generally less than 10,
Tap water varies depending on the region, usually between 100-400.
Precautions for use: Avoid soaking TDS pens in water, avoid direct sunlight and high temperatures, avoid impact, heavy pressure, and dropping. The difference in conductivity between TDS pens and TDS pens should be avoided
It's two different concepts, one is a physical quantity and the other is an electrical quantity, but the measurements are the same. Both reflect the quality of water. Conductivity measures the conductivity of total ions in water. Waterproof pens are divided into two types: conductivity and TDS. TDS is the content of solid substances dissolved in water. The value of TDS multiplied by 2 is approximately equal to the value of conductivity, but it is not the same
TDS value refers to the content of solid substances dissolved in water, measured in milligrams per liter. If your water purifier has little adsorption effect on dissolved substances in water, there will be no significant change in TDS value.
TDS value represents the total content of soluble substances in water, such as calcium, magnesium ions, and some trace minerals. TDS value in tap water is less than or equal to 1000 milligrams per liter, and water purifiers are used to purify water
Purifiers for harmful compounds such as sediment, rust, residual chlorine, and methane in the water will not reduce the content of beneficial soluble substances, so the TDS value of the purified water can remain unchanged. TDS is a numerical value, but not a standard for measuring whether water can be consumed directly
