Each TF test kit contains every necessary reagent to test your pool or spa water for the most important parameters, including free and combined chlorine (FC/CC), pH, total alkalinity (TA), calcium hardness (CH), and cyanuric acid (CYA). Learn more about these parameters here at TFP!

 The only difference between salt and non-salt kits is the addition of two reagents, R-0630 and R-0718, that are used to test for salt levels. The salt and non-salt kits use the same cases and feature all the same hardware.

You can save 10% on eligible add-on items with a test kit purchase.
