I've been using my new Digital Aid Total Dissolved Solids (TDS) meter for a few days now. It arrived quickly and well packaged. I wanted it because we had just installed a new reverse osmosis (RO) water filtration system here at home. The "Digital Assistant" is very easy to use, the instructions provided are quite easy to follow. In short, turn it on, place the tiny probes embedded in the water at one end. easy to read display. Voila! Well it got me measuring the water in our pond, the water outside. You will have fun checking the water sources around you. Compare your water to bottled water, which we did. can show that yours is better than popular bottled water. ours was.
