Protect members with Indigo® 400 ppm quat (QAC) sanitizer test strips in gyms, pools, and spas. Control pathogens on high-touch surfaces and meet public health compliance standards.
Fitness and recreation centers, including gyms, swimming pools, and spas, rely on strict sanitation programs to keep members safe. Regular quat sanitizer testing for high-touch surfaces such as exercise machines, locker rooms, shower areas, and poolside furniture ensures disinfectants remain effective. By confirming quat concentrations are within the recommended range, facilities can protect against pathogens like MRSA, E. coli, and norovirus that spread easily in shared environments.
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.
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 vs ppm results for commercial formulations of quaternary amine sanitizers/disinfectants from 20 to 60oC (68-140F).
T (oC/oF) | QAC strips readings at: 0; 50; 100; 200; 400 ppm |
20/68 | Readings ok for 0-400ppm |
25/77 | Readings ok for 0-400ppm |
30/86 | Readings ok for 0-400ppm |
35/95 | Readings ok for 0-400ppm |
40/104 | Readings ok for 0-400ppm |
45/113 | 0, 50, 100 ppm readings ok; 200 & 400 ppm read~ 1/2 color square higher |
50/122 | 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® brand test strips are Made in USA & tested for accuracy using NIST compliant standards.
Great product and great customer service!
Consistent product, that is used repeatedly, Shipping times are as expected. Online ordering is easy.
Great customer service! Contacted me to let me know there was a less expensive shipping rate available. Very helpful.
Great product, much more affordable than competitor prices. Quick delivery.
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.
Great product as always and excellent service.
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
Thanks for noting our prices. Our discounts start at just 2 it costs the same to as 1.
