Quick Check 4 in 1

Product detailed description

Instructions:
1. Immerse the strip in water and immediately pull it out.
2. Hold the strip horizontally for 15 seconds (do not shake excess water off the strip).
3. Compare the colour of the pad for free chlorine, pH, total alkalinity and stabiliser (in that order) with the colour chart on the label

The correct values are measured after just 15 seconds, do not compare values after a longer period of time.

In order to achieve crystal clear and hygienic water, it is necessary to measure the concentration values of the pool chemistry regularly (at least twice a week, more often at higher water temperatures).
