Pool-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.

Like our pooltesters, test sticks and comparators rely on visual assessment. The measurement result is not detected electronically. The human eye compares the measurement colour that results from adding reagents (e.g. tablets) with a comparative scale (colour disc).
The decisive difference between the comparator and all other visual measurement processes is that this one works with a color scale in the form of a rotating disc. The colour scale is placed around the disc without interrupting the colour and shows all possible colours in the measurement scale.
The water sample with reagents (10ml) is placed next to a reference sample (without reagent) inside the comparator. The appropriate disc is inserted and turned until the colour of the sample corresponds with the colour value on the disc.
The innovation behind Pool-i.d.’s comparators is in the adapter that is included. The adapter extends the sample’s path-length and thus enables a “Multi-Range Reading” without diluting the sample.
Depending on the parameters, the Pool-i.d. comparators work with Pool-i.d. reagent tablets or powder packs/foil packs made by wellknown Pool-i.d. partner companies.
