e easy-to-use test paper strips indicate the approximate strength of chlorine sanitizer solution in parts per million. To use, remove one strip from the vial using dry fingers and dip it into a solution of 50 ppm (parts per million) without agitation. Hold it in the solution for one second, then remove the strip and compare its color with the convenient color chart on the package label to see your results. That's all it takes.
