Why worry about a hydrogen peroxide dilution formula? Use our free hydrogen peroxide dilution calculator to take out the guesswork.


How to Test Hydrogen Peroxide

Hot tub hydrogen peroxide measurements are easy. Simply dip the indicator pad at the end of the strip into the water you want to test and compare to the color chart after 30 seconds. Results are accurate to within 10% and are a quick, reliable way to ensure you are protected against harmful germs.

Use our hydrogen peroxide dilution calculator to take the quesswork out of ensuring 100, 200 or 400 ppm hydrogen peroxide levels.

  • Indigo™2 year shelf life but these vials are lined with desiccant & so the actual strip shelf life can be 5 years or longer. Read: Sanitizer Test Strip Expiration; Good Today, Dead Tomorrow?

  • The number of strips per vial (100) is approximate.
  • Suitable for detection of hydroperoxides and ether peroxides. Polymeric peroxides, which can form in diethylether, are not detected. Organic peroxides, such as di-tert-butyl peroxide, dicumyl peroxide or tert-butyl perbenzoate, either do not react or react with significantly reduced sensitivity.
