Oto & pH 3-way test kit

Measuring the chlorine level:
Fill the test tube up to the mark with pool water. Make sure to sample water that comes from 50 cm below the water level and away from the pool inlets.

Add 5 drops of the Oto product (yellow vial).

Seal the test tube and shake to allow the product to spread.  After 10 seconds, you can read the free chlorine level and compare it with the ideal values.

After 5 minutes, you can read the total chlorine level. If there is a significant difference between these two levels, it is best to run a chlorine shock treatment.

Measuring the pH level:
Fill the test tube up to the mark with pool water. Here, too, it is best to sample water from a depth of approx. 50 cm and away from the inlets.

Add 5 drops of phenol (red vial). Seal the test tube and shake to allow the product to spread. After a few seconds, you can read the pH level. The ideal level lies between pH 7.2 and 7.6.

Caution: Store the test kit and products in a cool, dry place out of direct sunlight and away from children.

Follow the instructions on the packaging for testing the water quality. For best results, we recommend replacing the test kit every year.
