Hydrogen Peroxide H2O2 Test Strips, 0-100 ppm, 300-Pack

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

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.

Easy to use and read

I use the test strips to manage algae presence in my swimming pool. These strips provide the accurate measurements of H2O2 levels. I have calibrated their results against industrial laboratory samples and have found them to be very accurate.

Does the thing

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

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

I use these strips to measure the hydrogen peroxide concentration in my cold plunge. They work perfectly. I’ve been able to catch when something is in the water and is eating up the hydrogen peroxide quickly, which is super helpful. Sometimes you don’t know unless you measure because the water is still clear. I’m happy with these and will continue to purchase them!

Does what it says - when using the test strips, the colours really match the printed packet.

We use these to test our hot tub and they are very accurate.

Work very good and as accurate as my original strips for less money

Buona la funzionalità. Rapporto costo qualità un po' esagerato rispetto alla concorrenza.
