LCD Digital TDS Meter Tester Water Quality Ppm Purity Filter (TDS Tester)
The TDS Meter helps you put a number on what your taste buds are already telling you about what's in your water. It measures for totally dissolved solids in water that can give it a taste. The highter the reading on the water the more substances dissolved in your water.The meter is primarily used to indicate water filter replacement. It may also be used as a simple method to compare water quality by displaying the Total of the Dissolved Solids (TDS) in parts per million only. The meter does not specify what substances comprise the Total. The meter should not be used to assess the safety or purity of water, which should only be undertaken by a qualified laboratory.
