Description Water quality TDS test pen High precision drinking water test TDS
Total dissolved solids, abbreviated TDS, also known as total dissolved solids, measured in milligrams per liter (mg/L), it indicates how many milligrams of dissolved solids are dissolved in 1 liter of water. The higher the TDS value, the more dissolved matter the water contains. Total dissolved solids refers to the total amount of all solutes in water, including both inorganic and organic content. Generally, the conductivity value can be used to roughly understand the salt content in the solution. In general, the higher the conductivity, the higher the salt content and the higher the TDS. In inorganic substances, in addition to components dissolved in ionic form, there may also be inorganic substances in molecular form. Since the organic matter and molecular inorganic matter contained in natural water can generally be ignored, the salt content is also generally referred to as total dissolved solids. However, TDS in a specific water cannot effectively reflect the water quality. For example, in electrolyzed water, due to the significant increase of charged ions such as OH- in the electrolyzed water, the corresponding conductivity is abnormally increased. For example, the TDS value of the alkaline water obtained after the pure water with the original TDS of 17 is electrolyzed by an electrolysis water machine is about 300.

Easy to Use
you just remove the protective cap and immerse the PH meter electrode in the solution and turn on the PH by "ON / OFF" switch to be measured. Beats the heck out of trying to see the colors of a litmus strip.
Easy to Calibrate
You can simply follow the instruction on the provided packet of solution 4.01 or 6.86, immerse the PH tester in the solution and adjust with the provided screwdriver to dial it in.
Pocket Size
It's only 1.76 oz with size of 5.94*1.22*0.79 inches so that you can put it in your pocket wherever you go outside for a PH testing, it also comes with a handy storage case and dedicated screwdriver for calibrating.
Warning Tips
Be careful with the glass probe since it may be a little fragile when you use.
Remember to gently wipe it with a clean, soft cloth when you're done before capping it again.
