30 second response with readings at 0-100-200-300-400ppm for concentration levels of hydrogen peroxide.
  • Indigo™ test strips have a guaranteed minimum 3 year shelf life but are stored in desiccant lined vials so actual shelf life can be 5+ years.
  • For technical explanation, 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.
