Exact Industrial Test Systems Exact 486639-II Strip Micro pH

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.

Test results from one bottle to the next vary greatly, not what I expected, reading pH with previous bottle shows pH at 6.8 while new bottle shows pH at 8.0 (doing multiple reading to verify), both bottles used are well within their expiration dates. I expected more accuracy from this.

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

Fonctionne très bien avec ce type de machine. Livraison PRIME ma8s quand même eu un retard de 1 jour sur la date de livraison prévu au départ.

this product was ordered to check the PH on my pond and it does what it says on the tin

This item was required urgently and when it arrived the product information showed it was four months out of date and therefore not reliably usable
