Phenol red is a substance that reacts to changes in pH by varying its color from yellow to red-purple.
The test with OTO must always be carried out before the pH test as for high levels of chlorine or bromine the pH test may give incorrect results.
Always rinse the cuvettes well with the water to be analyzed before testing.
