Water-i.d.® comparators provide you with access to professional water analysis. While these comparators are also, like Pooltesters, visual measurement devices, the arrangement of the measured colour to the scale – and the determination of the measurement value – is much more precise with comparators because the measurement is compared on a rotating colour scale (colour disc). there are no measurement results “between” individual colour scales. ergonomic design and high-quality materials also simplify measurements. By using the adapter that is supplied with each comparator, the sample path length can be extended and additional ranges can be measured.
