Pooltester User Guide

The kit consists of a pooltester container, phenol red tablets, DPD 1 tablets, and DPD 3 tablets (optional). To ensure accurate results, it is essential to follow the guidelines provided in the user guide. Prior to testing, it is crucial to measure FRC between 30 minutes and 48 hours after chlorination of the water supply. Additionally, untreated water should not be added after chlorination of the water supply. The pooltester kit is designed to measure FRC levels by comparing the colour in the sample with the chlorine scale on the pooltester. The colour scale in the middle of the pooltester is used for lighter sample colours (lower chlorine levels), while the scale at the far right is used for darker sample colours (higher chlorine levels). The free chlorine test procedure involves adding a phenol red tablet to the left-hand compartment of the pooltester container. The sample water is then added to fill the compartment, and the rubber stopper is replaced. The mixture is shaken for approximately 20 seconds to dissolve the tablet. The sample is then allowed to stand for 2 minutes before comparing the colour with the chlorine scale on the pooltester. The total chlorine test procedure is similar to the free chlorine test, but it involves adding a DPD 1 tablet to the right-hand compartment of the pooltester container. A DPD 3 tablet is also added to the same sample containing the DPD 1 tablet. The mixture is shaken for approximately 20 seconds to dissolve the tablets, and then sample water is added to fill the compartment. The rubber stopper is replaced, and the mixture is shaken again for approximately 20 seconds. The sample is then allowed to stand for 2 minutes before following the steps outlined in the free chlorine test procedure. The pooltester kit is a reliable tool for measuring pH, FRC, and TC levels in pool water. However, it is essential to note that high levels of chlorine can remove the pink colour formed by DPD in the test, resulting in a false negative result. If this occurs, the water sample can be diluted with chlorine-free water and the test re-run.
