Ph reagent question

[ROB N]

I have two test kits and in my tf-100 I am running out of some reagents, I also have a Taylor k-2005 and some of the reagents are identical and I will be able to use those up before I reup my tf-100. But the k2005 has the ph reagent r-0004 and the Tf has r-0014. The r-0004 says to use with the 2000 series comparator and the r-0014 says to use with residential series comparator. Are the two reagents the same thus interchangeable. Or are there differences and what would they be??? :?

They have different concentrations, because the comparators hold different quantities of pool water. You have both comparators, so just use each reagent with the comparator/view tube that it came with.
