Hydrion QT-10 Quaternary Test Paper provides a simple, reliable means to measure the concentration of Quaternary Sanitizers, including n-alkyldimethylbenzyl and/or n-alkyl dimethyl ethyl benzyl ammonium chloride, and others like Rocall II.  This test paper measures concentrations between 0-400ppm, detecting exhaustion of solutions that should be replaced as well as helping to avoid using excessive amounts of sanitizing agents.

Each kit inlcudes a 15-foot roll of test paper and matching color chart.

To use, dip the strip into your sanitizing solution for 10 seconds, then immediately compare the resulting color with the enclosed color chart. Test solution should be between 65 and 75 degrees Fahrenheit.

Contact Local, State or Federal Health Department for Quaternary Ammonium Sanitizer concentration requirements. These concentrations may vary depending on your specific application.
