Ensure safe food at festivals, fairs, and pop-up kitchens with Indigo® 400 ppm quat test strips. Portable, reliable sanitizer testing for local health code compliance.
At festivals, fairs, community events, and temporary pop-up kitchens, sanitation is just as critical as in permanent facilities but the challenges are greater. Indigo® 400 ppm quat test strips provide quick, portable verification that sanitizer solutions are at the correct concentration, ensuring compliance with local health codes. Whether it’s a weekend food truck rally, a temporary outdoor fairground kitchen, or a religious gathering, proper sanitation prevents foodborne illness outbreaks and protects public health. These test strips are compact, easy to use on-site, and help operators pass surprise health inspections with confidence.
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 Community Events & Temporary Kitchens
Mix sanitizers fresh daily in portable containers.
Use Indigo® strips to verify sanitizer buckets and spray bottles meet 400 ppm.
Maintain logs during multi-day events to satisfy inspectors.
Keep sanitizer solutions separate from food prep surfaces to prevent residues.
Train volunteers and temporary staff on correct sanitizer use and testing.
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
