Details

You can use our bleach dilution calculator to correctly calculate the amount of bleach & water needed to prepare the ppm levels indicated above. This calculator will allow for any concentration of chlorine bleach to be used to prepare a sanitizing/disinfecting solution. Watch the video:

In the case of cruise ships, food borne illnesses could spread rapidly because of the relatively crowded conditions and overwhelm on board health care facilities. These high level, 1000ppm (0.1%) chlorine test strips will determine in seconds whether your chlorine bleach solutions are at the higher strengths required.

Simply dip a strip into the bleach solution, ensuring that the small indicator pad is fully immersed for a few moments. Withdraw the strip and compare to the color chart on the pack for immediate, accurate readings.

Test Strip Documentation

Stability Statement Certificate of Analysis

 

The following table shows how much bleach is needed to make up different concentrations of disinfectant based on an initial concentration of 5% (most store bought bleach sold in North America is rated at 5.25% but loses strength with time).

  1. Choose a container large enough to hold the final amount of diluted bleach you want to make.
  2. Measure & pour into the container the amount of 5% (initial) chlorine bleach you need.
  3. Fill the container with water to the level of the Final Volume.
  4. For concentrations other than 5%, use our Sanitizer Dilution Calculator to determine what you need. 
  5. If you are unfamiliar with millilitres (mL), you can use this Metric to American volume converter.
  6. If you don't have the exact measuring tool round up, not down.

After searching online for 1000 ppm test strips, I found these at Indigo Instruments, and they were exactly what I needed, plus very reasonably priced! In an era where it is hard to find good customer service, I was pleasantly surprised when Chris answered all my questions, and made sure the product I ordered was what I was looking for! He was super helpful and knowledgeable. We received the product quickly and would not hesitate to order from Indigo again. Thanks, Indigo!
