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

Very easy to use, very accurate. I have been using these for years.

Works as intended. To

way too much xpensive

I took a reading. The clorine was high ph was high and alkaline was high. I added ph decreaser and waited 12 hours. I took another reading. The clorine and alkaline went to 0. The ph actually increased. Do not waist your money on this product. I went through 3 bottles of chemicals and could not get hot tub chemical balance. The reason was this product is inaccurate. I threw product in garbage as it was beyond return date.

as described

Perfect

It does not record chlorine levels.

Item expired on arrival in April... 2023/04 printed on bottle bottom.

i try using the dip sticks and match the colour's but this is way better i get a number and no guess work . way better and super easy to use.

Ce ne sont pas les bandelettes mais bien la machine qui lit les résultats qui n'est pas parfaite ! Les bandellets eux sont bien correctes.

Bandelette pour spa au brome Super bonne lecture je recommande

Sadly, the machine these are used with is as inconsistent as a snowflake. I now have two bottles of useless test strips and an equally valuable machine they do not work with.

I purchased two bottles of these test strips. Although these arrived very quickly. THEY ARE OUT IF DATE. bottles clearly state “ USE BY DATE ON BOTTOM”. Date on both bottles is April 2023. It is now May 2023. Total waste of money.
