📏 Ultra-Precise Very Level Strips: Measures 0-10000 Ppm with Accuracy Review

After I put it to the test, I found these strips to be extremely precise and straightforward to use. The color changes are distinct and the results are easy to read. The best part is that I didn't need any additional equipment to use it. However, the only downside is that the strip isn't reusable, which can be wasteful.

Accurate as far as I can tell. Isn't that the meaning of the stripes, which you can't otherwise see? In any case, more dilute solutions will not register, so I assume they are indeed accurate.

These strips are suitable for higher concentrations, other test strips are available for measuring lower concentrations. The range is large, but results are read instantly, which helps ensure the resulting accuracy. These are plastic strips with a test pad at the end, very easy to use. Used them with concentrated solutions to find ppm and they showed 5000ppm as expected.
