HM TDS-EZ PPM PEN

We carry the TDS Water Meter, an excellent TDS water quality tester. This meter is very simple and easy to use and the measurement range is from 0-9990 parts per million (ppm). This meter is also very accurate in identifying the total dissolved solids in your water. We have a few other models for you to choose from, depending on what you're trying to measure and different options you'd like to have.
