Pooltesters are mainly used in the wellness sector and, even if the name doesn’t hint at it, they are also used for the analysis of drinking and industrial waters. In many countries, for example, drinking and industrial waters must be disinfected with chlorine which requires that they be subjected to consistent controls. hotels worldwide already use the Water-i.d.® Pooltester for guest swimming pools, and also to determine the quality of their drinking and general waters. Water-i.d.® Pooltesters are even used by well-known international aid organizations to also control drinking water plants in crisis regions. Here too, people rely on Water-i.d.®’s quality standards.
