TDS Meter to test total dissolved solids in water. A Must For All RO System Owners.
Simple to use for Reverse Osmosis membrane monitoring. Measure the incoming water and the RO water. Divide the larger number into the smaller number and subtract that decimal from 1. The resulting decimal is the percent of Total Dissolved Solids (TDS) that the membrane is removing. Replace membrane if less than 80% of TDS is being removed. TDS are the total weight of all solids (minerals, salts or metals) that are dissolved in a given volume of water expressed in milligrams per liter (mg/L), or in parts per million (PPM). The lower the TDS level in the water, the more efficiently your bodys cells actually get hydrated by the water that you drink. The higher the TDS levels in the water, the greater the probability of harmful contaminants that can pose health risks or hinder the absorption of water molecules on the cellular level. 17 PPM of TDS = 1 grain of hardness.
Is Total Dissolved Solids a measure of water quality?
No, total dissolved solids is not a measure of water quality to correctly measure water quality you need to have your water tested in a Lab.
