The Portable Digital Water Tester pen will read the TDS (Total Dissolved Solids) water values which will reflect on the LCD display located on the middle upper position of the pen. The detection sensor starts to function as soon as the metal comes into contact with the water being tested. The gadget is powered by means of two batteries located on the rear. You will have an accurate and stabilized reading in about three seconds of testing the water. It measures water quality on parts per million scale. Fast, easy and simple with huge benefits. Great for outdoors and camping.
In no time you will know the amount of mineral and water salts in the water. You will know the quality of the water when it matters most.
