Yellow 4-in-1 teststrips AquaChek 50 pieces

50 Pieces in a box.

Test strips for when you use chlorine in your pool or spa.

Also you can measure the value of the cyanuric acid content, this is important for outdoor pools and spas that are subject to chlorine degradation by UV rays.

With these test strips, you can measure four important values, including free chlorine, pH, alkalinity and cyanuric acid.

Easy-to-use easy-grip bottle with convenient top opening.

Chech the water before you use your pool or spa to make sure all the values are correct, when you stop bathing check the values again and adjust if necessary.

You should also note that the warmer it gets outside and when you have a lot of people in the pool or spa, you will need to measure more and add product to the water faster.

Store the test strips at room temperature and do not leave them in the sun, the pads on the test strips are sensitive to temperature when stored.

So close the box immediately when you have taken out a test strip.

Compare the colours with the back of the box after 15 seconds, the longer you wait the more the colours will deviate.

In short, measuring in knowing!
