Meat testing, clenbuterol residues, Escherichia coli, nitrite, parasites, etc. are hard to detect. Some viruses are difficult to remove under high temperature. In mild cases, indigestion does not absorb nutrients, and in severe cases, it induces disease14. Detection of nitrate content, dangerous nutrients in fish meat. During the process of raising fish, the nitrate content in the water is too much due to the lack of monitoring of water quality by the farmers. Once the nitrate is measured, it will be absorbed by the fish. high levels of dangerous nutrients15. Control the time, the taste is more delicious, too long cooking time will destroy the cell structure of the food, let the nutrients flow out, and some nutrients are more afraid of heat, at the same time, some vitamins and minerals will dissolve into the soup and lose a little bit , the longer the time, the more loss16. Dimensions: 122x52x14mm17. Weight: 85 gramsSteps:Step 1: Push back lightly to open the cover and clean the probe before testingStep 2: Press the upper button to power onStep 3: Select fruits and vegetables from the menu for testingStep 4: Insert the probe directly into the middle of the pulpStep 5: Press start test, get the result in 3 seconds

1. Applicable scenarios: home, hospital, swimming pool, disease control center, water plant laboratory, aquaculture industry2. Detectable range: 0-99903. IPX6 waterproof body, prevent a lot of water splash4. Powered by two button batteries (included)5. Can detect three types of impurities in water:- Calcium ions, magnesium ions and other soluble salts- Ammonium acetate, sodium sulfonate and other ionic organic substances- Heavy metal ions such as chromium, zinc, lead, and copper6. The water quality varies from country to country in different regions. The TDS test pen can accurately detect the TDS value of water, and can detect the purity of water before and after filtration, which reflects the filtration capacity of the water purifier. In general, the lower the TDS value, the less dissolved solids in the water and the purer the water quality.7. We cannot intuitively understand the purity of drinking water. Seemingly clear and transparent water may contain many impurities. The TDS value represents the total soluble solid content in water, which can reflect the water quality to a certain extent. Generally, the lower the TDS value, the less soluble salts such as heavy metal ions in the water, and the purer the water quality. The World Health Organization (WHO) generally believes that the taste of water with a TDS value below 600 is good or appropriate. When the TDS level is greater than 1000, the taste of drinking water will change significantly.8. High-precision technology makes detection more accurate, waterproof design of the whole machine, low power consumption chip9. The TDS value of water can be accurately known without complex chemical tests. Just put the water quality TDS test pen into the water to be tested, press the switch, and the display will immediately display the TDS value of the water to let you know the purity of the water.10. Size: about 13x4 cm11. Weight: about 25 grams
