AquaChek TruTest Refill Test Strips - Digital Test Strip Reader Refill Strips - for Pool and Spa Water Testing - for Free Bromine, Free Chlorine, pH, and Total Alkalinity - 50 Strips

This are the best Test Strips ever. But it is not easy to find it. Thanks Pool Zoom

I have used the AquaChek Test Strips with the AquaCheck monitor devise for about 8 years and find the unit accurate based on the clearness of the pool water based on the AquaCheck readings. The unit is well worth the $$ as long as you take care of the unit and store without the batteries during the winter months. The test strips are competitively priced Amazon and arrive in 1 or 2 days for Prime customers. The strips and unit are not always sold or supplies on-hand at the local pool dealers or retail, but are always available on Amazon. If you want an easy to use accurate pool chemical tester, this one is recommended.

Wonderful product

I’ve used these for years. I’m not sure if they’re totally accurate? Comparing them to dip strip- they usually show a different reading? Other posts state sunlight can affect the readings…???

Order every years. Work perfectly

Strips work great. My old strips were expired and misreading the pH. New strips solved this issue.

Chlorine seems to be fairly consistent, but the ph and alkalinity are all over the place. Example I tested for ph and it read 8.0 and 5 minutes later another strip read 6.9!!!!! Same inconsistency with alkalinity.

Takes the guess work out of testing. I can show the color test strip to three different people and get three different answers. The only thing is you MUST take the water inside, out of the sun to test. It is an investment because you need the reader, but so is your pool. I test every week. Once the pool is where it needs to be that is it. Highly recommend this to anyone that wants to properly maintain their pool.

Todo bien

Conforme au produit que j’achète habituellement pour quasi le même prix chez le revendeur local. La date de péremption de l’article reçu est assez proche. Dommage, ce produit perd de son efficacité en vieillissant

Funziona bene

One of the best test strips there is only thing is you have to have the test metre to go with it which is expensive the test strips themselves out twice the price of regular test strips but give very accurate readings they are a must if you have a hot tub 5*****
