Can someone tell me what range of Cl the TF-100 kit will test to. Can it test to say 20, or do you have to dilute your water sample and multiply for numbers above 5. Thanks.

There are two chlorine tests in the TF-100. The better one will test chlorine up to at least 50 to the nearest 0.5 (or 0.2 using alternate directions). The simpler "quick test" only goes up to 5.
