AquaChek 422012001 TruTest Test Strips Refill Pack - Chlorine pH and Alkalinity - 50 Strips

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*****

This gives a steady result every time used and takes the guess work out of the readings, I find it is worth the money to take away the hassel and keep the softub running.Great value for money

I bought this as a refill so I could continue using the test meter. I find it accurate in that I have had no issues with our hot tub vis-à-vis corrosion or unsafe water. I use chlorine in our tub so it is important that I regularly check the 'Ph' level, and total alkalinity, so the meter and the strips are an easy way of doing this.

Checking the chemical balance in a swimming pool is always a pain. The AquaChek method means you don't have to compare colours with the printed examples on the tub - always a bit unreliable and the examples can fade. With this system, just dip the 'stick', rest it on the machine, press the button and wait. An exact reading is displayed - and stored in case you need to check later.

With an AquaChek device, measuring pool chemistry could not be easier, and much more accurate than the traditional colorimeters.Packaging in airtight containers of 50 strips is convenient and avoids frequent re-ordering. The price was sensible, and delivery was prompt.

Exactly what I wanted.

these work really well with the machine reader i have would buy agin

I have used aquachec test straps for a number of years and find them easy to use and very accurate when compared against other pool test items
