The Quaternary Ammonium (QAC, Multi Quat) Test Paper, 0–1000 ppm is a fast, dependable solution for monitoring the strength of quaternary ammonium sanitizers used in foodservice and sanitation environments. Designed for ease of use, these paper test strips provide clear, visual confirmation of sanitizer concentration through distinct color blocks at 0, 200, 400, 600, and 1000 ppm.
QAC compounds are microbicidal to most microorganisms at approximately 200 ppm, making accurate verification essential for both safety and regulatory compliance. This kit enables users to ensure sanitizers are neither under-dosed—reducing effectiveness—nor over-dosed, which can waste chemicals and violate usage guidelines.
Each vial contains 100 paper strips and requires no specialized training. Simply dip the strip into the solution for one second, allow it to develop for 5–10 seconds, and compare it to the included color chart. The kit is suitable for routine checks, including recommended two-hour retesting, and supports compliance with health codes that mandate verification of quaternary sanitizer strength.
When stored properly in a closed vial, at room temperature, and out of direct sunlight, these test papers deliver consistent, accurate results across a wide range of commonly used quaternary sanitizer formulations.

INSTRUCTIONS:

1. Remove a test paper from the vial, being careful not to touch the strip anywhere other than where you grasp it with your fingertips.
2. Dip about 1″ of test paper into the solution to be tested for 1 second.
3. Allow 5-10 seconds to develop, then compare to the color chart.

NOTE: The test strips should be kept in closed vials when not used, out of direct sunlight, at room temperature." Wide QAC Test Range: Measures quaternary ammonium sanitizer concentrations from 0–1000 ppm, with clear color blocks at 0, 200, 400, 600, and 1000 ppm for fast, reliable interpretation. Foodservice & Sink Compliance: Ideal for three-compartment sinks and routine sanitizer verification in foodservice, institutional, and commercial sanitation programs. Regulatory Ready: Meets federal, state, and local health department requirements for verifying the strength of quaternary-based sanitizing solutions. Broad Chemical Compatibility: Guaranteed accurate with common quats including OASIS 146, Hyamine 35, Bardac 2250, Sysco tablets, and other alkyldimethylbenzyl ammonium compounds. Simple, No-Training Required: One-step dip-and-read format allows non-technical personnel to quickly confirm proper sanitizer concentration and avoid overuse or solution exhaustion.
