Test industrial-strength quaternary ammonium sanitizers up to 10,000 ppm. Ensure effective sanitation in food plants, breweries, and pharmaceutical facilities.
Food processing plants, beverage production, dairies, breweries, and pharmaceutical facilities, have sanitizing surfaces that require higher levels of quat disinfectant than those in restaurants or janitorial cleaning. Residual organic load, high equipment contact, and strict HACCP / GMP compliance demand accurate testing.
Indigo® 10,000 ppm quat test strips allow operators to verify the potency of concentrated sanitizers in industrial sanitation programs. Unlike lower-range strips (0–1500 ppm), these confirm that sanitizers remain effective even in high-load conditions. Using high-range strips prevents both under-dosing (ineffective sanitation, contamination risk) and over-dosing (waste of concentrate, equipment corrosion).
We've been selling quaternary ammonium (quat) test strips since 2007. Buy fully documented Indigo® QAC test strips, 100 strips/pack with a guaranteed 3 year shelf life (dated back from expiration date "yyyy.mm.dd"); see storage requirements in Specifications.
Dip strip & remove for immediate readings at 1000-2500-5000-10000 ppm for quaternary ammonium disinfectant concentration. Read strip results immediately. If you wait the 30 seconds needed for some other strips you will get a reading that is too high.
A Certificate of Conformance is available on request after shipment.
Indigo® Quat (QAC) test strips are made in USA & calibrated with NIST standards.
QAC test strips use various surfactants, buffers, and indicators to employ the protein-error of indicators effect.

Great Service! Easy to order and great customer service!
Easy to order online, shipment was made in a efficient timeline. Test kits appear to be working but need further experimentation to ensure results are consistent over time.
