Hydrogen Peroxide H2O2 0-100 ppm Test Strip Kit, Low Level [Vial of 100 Strips]

I use these strips to measure out the hydrogen peroxide in my cold plunge and they work very well.

Easy to use and read

I bought these to test the peroxide levels in our hot tub, which we're disinfecting with hydrogen peroxide rather than toxic chlorine.. They work really well.. I have a consistant reading between 50-100 ppm's, which is very good.. Just to make sure they work, I tested one in a glass of tap water and it didn't turn any color at all, which indicated to me that they are indeed giving an accurate reading. Price is very fair, too.

These have been a game changer for maintaining my cold plunge!

Exactly what we needed for our stock tank pool that we use hydrogen peroxide in instead of chlorine.

tried another brand and no luck. these seem fairly accurate.

We use these test strips to measure the hydrogen peroxide concentration in the drinking water after sanitizing the storage tank on our sailboat and to check when the concentration drops to a safe level for drinking. The strips work well but seem too expensive for what they are, hence four stars instead of five.

Got allot of testers for tires money. No problem with them not showing levels. Great value
