Review on 🚰 Beslands Temperature 0-9990PPM: Ultimate Solution for Drinking Water and Aquariums by Nathan Vaughn

Total Dissolved Solids (TDS) meter came with well made portable case and battery. On the back of the meter is a handy chart showing water purity with clear labels explaining each category of water purity. After switching on, the measuring device was immediately ready for the water test. I immediately set out to find a measurable difference between my tap water and reverse osmosis water. I dipped the meter in tap water and the screen immediately turned red. My tap water was 222 ppm, which according to the chart on the back of the meter is the minimum acceptable average for tap water. I then tested the water in the reverse osmosis system and, to my surprise, it showed a purity level of only 37 ppm, which according to the table corresponds to excellent purity. Overall I am happy with the results of this instrument and would definitely recommend it for testing water purity.
