Fast response Indigo™ brand 0-1500ppm quaternary ammonium chloride sanitizer test strips for high level hospital & dairy disinfection quat sanitizers, only $11.75/100 strips, save on quantity.

Note: Read immediately. If you wait the 30 seconds needed for some other strips you will get a reading that is too high.

Concerned about strip expiration? Read our blog Sanitizer Test Strip Expiration; Good Today, Dead Tomorrow? Even if you only use 1 strip every second day, you can buy multiple packs for greater savings & not worry about expiration.


I need to create a Standard Operating Procedure on how to use and interpret the use of the High level QAC test strips. I found the one page document on the product description and operating principles I wanted to know if you had any training videos or additional documents on describing what is the desirable ppm range the foot bath should be in, on understanding how to read the strips and what to do if the strips are not within the desirable range. My operator is VERY new and I need to explain every detail.

1. If you don't have guidelines set by a local health authority or an industry standard, then go with the highest level, 1500ppm. However, some have even gone with higher levels and use the 10,000ppm strip.

2. The instructions on the strip pack are straightforward. Dip the strip into the solution & IMMEDIATELY compare to the color chart. If you wait 30 seconds, as required by other brands, you will get a false high reading.

3. Do not use hot water. Water warmer than 40C/105F may give false high readings.

4. The simple answer for not in the desirable range is to add more Quat concentrate if the reading is low. Add more water if the reading is high. Then retest. Don't worry about being exact, you can be +/- 10% without major consequences.

If you run into repeated problems with getting the right concentration, try our Dilution Equation Calculator.
