    Its what I use
  

*by S***T on Reviewed in the United States on 2 March 2024*

In fairness I haven't always and only used this test kit. However it has been the most reliable compared to others. It also closely matches my math in certain cases. Though not as precisely as I'd like it is usually close. Colorimetric titrations out of dropper bottles can only get one so close. Unless you break out a lab burette you can't get much better. It is designed for a certain range it works perfectly in that range for typical use.
