Water-id FD55 pH 4–10 Comparator Kit
Water-i.d.® comparators give you access to professional water analysis. Although, like the Pooltesters, these comparators are visual measuring instruments, matching the measured colour to the scale and determining the measured value is much more precise with comparators, because the reading is compared on a rotating colour scale (colour disc). There are no measurement results “between” individual colour scale values. The ergonomic design and high-quality materials also make measurement easier. Using the adapter supplied with each comparator, the sample path length can be extended and additional ranges can be measured.
