I bought the TF-100 test kit and love it. It is so much more accurate than the traditional strips and those basic kits. But I was disappointed there was no specific test for PH other than the k-1000 test kit. The instructions even say not to record results from the K-1000 because it is just a 'gauge' for the Chlorine and PH measure. But what about the PH? Is there a more accurate test where you count the drops of reagents used as appose to looking through a colored chamber/chart?
