Ensure proper strength of quaternary ammonium disinfectants up to 10,000 ppm in schools, prisons, gyms, and healthcare facilities.
Large-scale operations such as hospitals, nursing homes, correctional facilities, schools, and fitness centers often require stronger disinfectant solutions than those used in household cleaning. High traffic, diverse surfaces, and the risk of pathogen transmission (MRSA, norovirus, influenza, Candida) make reliable disinfection a priority. Indigo® 10K ppm quat test strips provide fast, accurate confirmation that institutional grade disinfectants are at the proper concentration.
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.
