AquaChek TruTest Test Strips (100 Count) (1)

These test strips provide relatively consistent results when used with the AquaChek TruTest Digital Test Strip Reader. It eliminates the effect of personal bias and the effect of background illumination. I highly recommend these test strips for measuring free chlorine, pH and alkalinity in your swimming pool.

Test strips work well for testing the pool water

Very easy to use and the best way to check the levels in the hotub.

These strips are an easy way to keep track of the chemicals in our hot tub. It’s like test strips for dummies!

Timely delivery and works perfectly to check the chemical balance in my swim spa. My skin is highly sensitive so I very accurate water/chem balance checks.

It’s difficult to find these test strips anymore but these work perfectly for the Aqua check reader.

I purchased these test strips because they're a hundred count bottle of test strips.I like to dip the strips down into the spa water, up to the middle of the forearm. I swirl the strips around in the water for a couple of seconds and when I pull the strip out of the water hit the test button, flick my arm and strip a couple of times and quickly place the test strip into the reader. I keep a cotton tip swab at the ready to pre-clean the colorimeter glass before dipping the test strip in the spa. I place the test strip in the reader slot and hold the test strip in place with the cotton swab laying the length of the test strip. I take three readings so I can get a trend line for the spa water chemistry.Overall, when tests are done in this fashion, you'll need a boatload of test strips and the more you test your water, the more you'll need this product for the convenience having so many strips provides. Also, buying large numbers of test strips like this, if you have to pay for postage you'll save by having to make less purchases. This is a good thing.Hope the above helps.

I got results that were all over the place using a single drawn sample of pool water. I have a better test kit coming.
