Analytical strips 3 parameters: free chlorine

Analytical strips

Ideal for: Daily water analysis of all types of residential pools and spas.
These analyzes help keep water sparkling clean, prevent corrosion and prevent sudden changes in pH.

Immerse one strip in pool or spa water for one second and remove immediately.

You'll get scan results in seconds.

To keep the pool in top shape, test at each end at least 2 times a week, and at the spa, before each use.
It's also a good idea to write down the results each time you run a test, to keep track of any changes.
