Cleaning, sanitizing & disinfecting surfaces are the 3 steps you need to take to keep children in your care healthy and safe at child, youth and school services. Do this for food preparation & contact surfaces such as countertops, plates, utensils, pots, pans, cups, cutting boards, stove, oven, grill, ventilation/exhaust hood, microwave, food warmers, carts, tables, highchairs & waste receptacles.

The color chart has ranges for sanitization (50-200ppm) & disinfection (500-800ppm). 800ppm is considered the maximum level for child safety in the event of ingestion. You may also want to look at the following 2 pdf files from the State of California for "Sanitize Safely & Effectively" & "What is Safe & Effective Use of Bleach"

Use our free Chlorine Bleach Dilution Calculator to calculate the amount of bleach & water needed to prepare any ppm levels. You can use any concentration of chlorine bleach to prepare a sanitizing/disinfecting solution but as an example the video shows an 8.25% solution diluted to produce 650ppm (the midway point of 500-800ppm for disinfection as shown on the color chart).

The test strips themselves are reliable, the shipment is expedient, and the cost is comparable. This is my 4th order with Indigo and they will continue to have my business.

Thank you for kinds words.  Happy we can continue to provide these for you.


One of the only places we can purchase these strips that are mandatory for use in our business. Prices are very reasonable. Fast, easy ordering and they get here quickly. What more could a business want?

Thanks for the great feedback.


We use the Indigo™ brand 0-2000ppm chlorine test strips daily at work to test inhouse made hypochlorous acid (HOCl-). The range of the test strips is perfect as we use 500 ppm to 1500 ppm depending on the application. This products gives me the security to know that the product we are making is going to disinfect properly. I will be ordering this product again. Thank you.

Great to hear that. Nice to get feedback from someone who actually produces disinfectant.



I write this positive review as a private researcher. My career spanned five decades at the University of California at Berkeley as a manager of shared research facilities. I treasure no nonsense solutions to problems. I am pleased to write a review for Indigo Instruments which is positive. The company's a pleasure to do business with and their test-strips have greatly simplified my efforts in Andean orchid preservation using asymbiotic in vitro propagation.  Robert Hamilton,  Berkeley, CA

Thanks for e-mail explaining how you use them. "I use your strips to measure HOCl concentrations in solutions I make by hydrolyzing KCl. Plants like K but not Na; hence, I don't use Clorox as most tissue culture labs."  Using hydrogen peroxide test strips in greenhouses is more popular, nice to know about a different application. 

Great web site. Impressed with quick delivery. Will definitely be ordering again

— Indigo: Happy to help with the testing needs of your company.

We operate an Adult Daycare program and our local supplier, for these strips, stopped carrying them in the strength we needed several years ago. I found Indigo online and we get fast, efficient service with good pricing. Website is very "User Friendly". Very satisfied with this Vendor.
