Fill the test tubes with the water to be tested, add the pH reagent into the designated test tube, place the test tubes in the comparator, and read the value obtained on the color chart.
Refill compatible with the JBL PROAQUATEST pH 6.0–7.6 kit. The reagent refills allow for extended use of the test without purchasing a complete kit.
