The Hydrion QT-10 is a type of test paper (or strip) used to measure the concentration of 2-chain Quaternary Ammonium Sanitizers (Quats), like Roccal II, in solution, typically in the 0-400 parts per million (ppm) range, with color matches at 0, 100, 200, 300, and 400 ppm, essential for food service and healthcare to ensure proper sanitizing strength for health code compliance and effective germ killing. Users dip the paper into the sanitizer solution for about 10 seconds and compare the color change to the chart on the container to verify if the concentration is too weak (ineffective) or too strong (potentially hazardous).

Key Features & Uses:
Measures Quat Concentration: Specifically tests for 2-chain quaternary ammonium compounds.
Range: Detects concentrations from 0 to 400 ppm.
Color-Coded: Provides immediate visual confirmation with color matches at 0, 100, 200, 300, and 400 ppm.
Compliance: Helps meet health department regulations for sanitizer strength.
Prevents Issues: Avoids using solutions that are too weak (won’t kill germs) or too strong (can cause chemical burns or leave residue).

How to Use:
Prepare Solution: Make your sanitizer solution according to the manufacturer’s instructions.
Dip: Take a strip, dip it into the sanitizer solution for about 10 seconds (do not stir).
Compare: Immediately compare the color of the strip to the color chart on the dispenser or vial.
Adjust: Mix fresh solution if the concentration is too low or high.
