    Measuring CC

    My DPD test kit can measure free chlorine (FC) and total chlorine (TC). The difference is supposed to be combined chlorine (CC). It is hard to tell exactly what the difference is between the FC and TC readings. Is there a more accurate way to measure CC directly?

    Welcome to TFP!

    Yes, with an FAS/DPD chlorine test you can more accurately measure FC UP to 50 ppm and more accurately measure CC too. Get one at TFTestkits.net If you don't already have a good test kit get a TF-100, it includes the FAS/DPD test.
