Do bromine test strips work chlorine?

The only real difference between the two chemicals during testing is that the bromine weighs much more than the chlorine. In fact, bromine weighs 2.25 times as much as chlorine. When testing, we always record the chlorine and bromine residual levels as “parts per million” (ppm).
