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.

Display Type:Digital With Backlight Or Not:No DIY Supplies:Electrical Product Description A TDS meter (aka ppm pen, nutrient tester, tds stick) is an inexpensive and convenient digital tool to instantly check your overall water quality. TDS = Total Dissolved Solids, which is any salt, metal or mineral in the water. With the push of a button, the TDS can tell you your overall water purity level,which will be displayed on the screen in ppm (parts per million). The lower the TDS level, the purer the water, with 0 ppm being pure H2O. The TDS is great for checking your tap water quality, or knowing when to change a filter. (The meter does not test for biological contaminants.) The TDS is a great tool for drinking water,water filtration and purification, colloidal silver, hydroponics (test your nutrients), aquariums, RO/DI systems, pools and spas, commercial and industrial applications and more.
