Phenol Red Tablets Information
Phenol Red Tablets are used to test for pH levels in your water. They are used in conjunction with our Lovibond Pooltesters.
To use fill the comparator with water from your pool or spa. Put one tablet into the pH tube. Replace the lid and shake slightly to help tablet dissolve and then compare the water colour on the chart.
Please read instructions on the products before use.
