Hydrion Chlorine Test Paper provides a simple, reliable, and economical way to measure the concentration of free available chlorine in sanitizing solutions. Test strip size is 2" x 1/4".
Health regulations require users of chlorine-based sanitizer solutions to regularly test the chlorine concentration. Simply dip a strip into the sanitizing solution, blot with paper towel, then compare the resulting color with the matching color chart. Target chlorine concentration is 100ppm.
With color matches at 10-50-100-200ppm, the test paper measures concentrations between 10-200ppm.
Store unused test paper in a dry location away from sunlight for maximum shelf life.
