Hydrion QT-10 Quaternary Test Paper offers a simple, reliable, and cost-effective solution for measuring the concentration of Quaternary Sanitizers, including n-alkyldimethylbenzyl and/or n-alkyl dimethyl ethyl benzyl ammonium chloride. These test strips provide color matches at 0, 100, 200, 300, and 400 ppm (parts per million), making it easy to measure the concentration range of 0-400ppm. The test strips help detect the exhaustion of sanitizer solutions, ensuring they are replaced before becoming ineffective, while also preventing the overuse of sanitizing agents. Essential for businesses in compliance with federal, state, and local health regulations, the QT-10 test strips ensure that sanitizers are at the correct concentration, as specified by the manufacturer.
