This kit is very useful if you are unsure about the quality of your tap water. I bought it to test my tap water and to test the new filter I recently bought. It helps me decide whether to use a water filter or not. Below are the pros and cons. Benefits:-1) Get both a PH meter and a TDS meter in one package 2) Easy to use 3) A user guide is provided for both instruments 4) Includes a calibration package (three) with different pH values to order to calibrate the pH meter when 5) Material quality is good 6) Fast reading 7) Good design 8) TDS meter shows three different things 1) Conductivity 2) TDS 3) Water temperature 9) TDS meter shows four different modes . Two for conductivity and two for TDS with different units. You can use grade C or grade F as you prefer. 10) Good for home use to test drinking water quality. Cons: - I haven't found anything yet.
