No, The inexpensive HTH six way test kit includes the OTO chlorine test which measures TC (total chlorine) from 0 to 5 (though anything 3 or higher looks the same to most people). TC = FC (free chlorine) + CC (combined chlorine). You want FC, you don't want CC. Often CC is zero, and TC = FC. But with that test kit things can get confusing when CC is above zero.
