Exact Industrial Test Systems Exact 486639-II Strip Micro pH

They get the job done

Exact-ly what I needed. Now I can do all my pool water testing without taking a sample to the pool shop.

Seems to me that every testing method I use gives me a different result. I have spent time chasing the readings but decided that the only way to go was find and trust a single system. I am using an Idip meter and these strips. I have a pool and spa that use no chlorine and the two reading I need to be accurate are pH and copper. Using this system and trusting the results Seems to be working and after a number of years the results are good water and positive control. This is following the instruction that came with my system. Now and again my pool guy, I do not allow them to do anything with the chemistry, will show me a test that differs from mine and I have to admit that the equipment used seems very good and he is a professional. But clear water and a lack of problems convinces me that I am on the right track.

Works great just what I was looking for- great price!
