What is the best TDS level for drinking water? Ans: Generally, the TDS level between 50-150 is considered as the most suitable and acceptable.

Total dissolved solids (TDS) are the total weight of all solids(minerals, salts, or metals) that are dissolved in the given volume of water, expressed in milligram per liter (mg/L) or in parts per million(PPM).

TDS Range: 0 – 9990 ppm
Temp. Range: 0 – 80 degrees Celsius
Resolution: 0-999: 1 ppm; 1000-9990: 10 ppm
Temperature Resolution: 0.1 degree Celsius (Celsius only)
Accuracy: +/- 2%
Power source: 2 x 1.5V button cell batteries (included)
Dimensions: 15.5 x 3.1 x 2.3cm (6.1 x 1.25 x 1 inches)

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-3 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-3 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-3 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. The TDS-3 is a rugged model that includes a protective carrying case. This is the world’s most popular handheld TDS meter for industry professionals.
