HiSense Ultra 0.1

TEST RANGE:

A semi-quantitative procedure provides the total chlorine concentration between 0 and 3 ppm by comparing the reacted indicator pad color to the color chart on the bottle label. Color blocks represent total chlorine concentrations of 0, 0.1, 0.5, and 3 ppm.

Qualitative estimation of the residual bleach concentration in the rinse stream can be made by examining the indicator pad for the appearance of any pink/purple/gray color.
