### ⭐⭐⭐⭐⭐ Great find

### ⭐⭐⭐⭐⭐ accurate pH interpretation
*by S***R on June 19, 2024*

intended to work with Taylor 2000 series of test kits. I think one drop of R-0004 is equivalent to 5 drops of R-0014 test reagent. I use the R-0004 with my 1000 series test kit, using just one drop to pH test instead of 5 drops of the R-0014 reagent. Test it yourself if you own both reagents.
