FAQ & growing tips
How “accurate” is a reagent test compared to a digital meter?
It is a practical method for quick checks, based on color comparison. For very frequent measurements or numerical records, an electronic meter can be more convenient.
Why can the color be difficult to interpret?
Lighting, sample turbidity, and residues in the vial can affect it. Use a clear sample and always clean the vial.
How many tests can I do with one bottle?
The manufacturer declares up to 500 tests with the 30 mL format.
