Ensure resident safety in senior & independent living homes with quat sanitizer testing. Indigo® 400 ppm quat (QAC) test strips help meet regulations, maintain food safety, prevent pathogens, and assure compliance.
Senior and independent living homes rely on strict cleaning protocols to keep vulnerable residents safe. Regular quat sanitizer testing helps ensure that disinfectant concentrations remain effective against pathogens such as E. coli, Salmonella, and Staphylococcus aureus, which pose serious health risks in communal settings. Consistent testing not only supports infection prevention but also ensures compliance with government regulations for long-term care facilities and enhances trust with families choosing senior living.
All Indigo® Quat (QAC) test strips come in 100 (not 50) strips per pack & 3 year minimum guaranteed shelf life backed by a Certificate of Analysis, Stability & SDS documents as listed below; Certificate of Conformance on request. Be prepared for any health & safety audit or inspection.
Best Practices for Senior & Independent Living Homes
Test quat sanitizers daily in kitchens, dining halls, and medical treatment areas.
Keep a testing logbook for regulatory inspections and internal audits.
Train staff in correct dilution procedures to avoid under- or over-concentrated solutions.
Rotate disinfectant products to reduce resistance risk and ensure broad pathogen coverage.
Pair quat testing with pH and temperature checks when applicable to maximize disinfectant efficacy.
This test strip can measure the strength of many multi-quat formulations of single, dual and 4-chain quat disinfectants as listed in Quaternary Ammonium Compounds. You can even compare their chemical structures with the Indigo®3D Molecular Model Builder.

Temperature and QAC strips reading relationship
Temperature vs ppm results for commercial formulations of quaternary amine sanitizers/disinfectants from 20 to 60oC (68-140F).
50, 100 ppm read~ 1/2 color square higher; 200, 400 ppm read 1 color square higher
55/131
Readings 1 color square higher across whole range
60/140
Readings 1 color square higher across whole range
Dip strip for 1-2 seconds & get readings in 10 seconds at 0-100-200-400 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.
Indigo® test strips have a guaranteed minimum 3 year shelf life but are stored in desiccant lined vials so actual shelf life can be 5+ years.
They work wonderfully, was so happy to finally solve my sanitizer testing problems and to use hot water is great as well.

Thanks for letting us know your experience with hot water. The chemist who designed the strips even provided us with instructions on what to expect when using hot water with quats.

Excellent product- temperature range is far more liberal and fits our needs. State surveyor recommended! Down side is cost may be a factor considering old strips are provided for free from our vendor.

If you are using old strips, be careful as they may not be accurate. We in fact guarantee ours for 3 years minimum.Â
