Daycare regulations require testing chlorine concentrations for both sanitizing & disinfecting. Indigo brand 0-2000ppm chlorine test strips do both for only $15.50 per 100 strips.
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.
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 but in this instance 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).

Guaranteed 2 year shelf life but can last 5 years if unopened.
These strips measure free (available) chlorine
The number of strips (100) per vial is approximate.

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).
Choose a container large enough to hold the final amount of diluted bleach you want to make.
Measure & pour into the container the amount of 5% (initial) chlorine bleach you need.
Fill the container with water to the level of the Final Volume.
For concentrations other than 5%, use our Dilution Calculator to determine what you need.
If you are unfamiliar with millilitres (mL), you can use this Metric to American volume converter.
If you don't have the exact measuring tool, round up not down. i.e. for 47.5ml use a 1/4 cup.
Easy use of website, Quick delivery. Great customer care.

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.
