Hydrion QT-10 Quaternary Test Paper provides a simple, reliable, and economical means to measure the concentration of Quaternary Sanitizers, including n-alkyldimethylbenzyl and/or n-alkyl dimethyl ethyl benzyl ammonium chloride, and Rocall II. With color matches at 0-100-200-300-400 ppm (parts per million), the test paper measures concentrations between 0-400 ppm, detecting exhaustion of solutions that should be replaced as well as helping to avoid using excessive amounts of sanitizing agents.
Sanitizer solutions are essential in the food service industry to ensure that sanitizers are at the proper concentration specified by the individual manufacturer.
Dip the strip into the sanitizing solution for 10 seconds, then instantly compare the resulting color with the enclosed color chart which matches concentrations of 0-100-200-300-400 ppm. Test solution should be between 65 and 75 degrees Fahrenheit.
