JBL ProAquaTest pH 6.0–7.6 – pH water testJBL ProAquaTest pH 6.0–7.6 is a precise drop test for freshwater aquariums. It comes with a laboratory comparator system, colour scale, 2 glass cuvettes and reagent – sufficient for approx. 80 measurements.The JBL ProAquaTest pH 6.0–7.6 is an easy-to-use drop test for accurately determining the pH value in freshwater aquariums. The measuring range from pH 6.0 to 7.6 is particularly suitable for community aquariums, planted aquariums and aquascapes where a slightly acidic to neutral pH value needs to be maintained. A stable pH value is important for the well-being of fish, shrimps and plants. As many dissolved substances in the water are affected by the pH value, significant fluctuations should be avoided. The JBL test helps to detect changes at an early stage and to check water parameters regularly. Thanks to the laboratory comparator system, any natural colouration of the aquarium water is compensated for. To do this, one cuvette is filled with aquarium water and reagent, whilst a second cuvette serves as a control sample. The value is then read off the colour scale. The test kit is sufficient for approx. 80 measurements and contains reagent, 2 glass cuvettes with screw caps, a pipette, a comparator block and a colour scale.Your benefits at a glanceDrop test for determining the pH valueMeasuring range: pH 6.0–7.6Suitable for freshwater aquariumsIdeal for community aquariums, planted aquariums and aquascapingPrecise monitoring in the slightly acidic to neutral rangeLaboratory comparator system compensates for the water’s natural colourEasy to use with colour changeFor approx. 80 measurementsHelps to detect pH fluctuations at an early stageInstructions for useFill the cuvettes with aquarium water in accordance with the instructions. Add the reagent to one cuvette, place both cuvettes in the comparator block and compare the colour with the colour chart provided. After the measurement, the cuvettes and syringe should be rinsed thoroughly with clean water.When setting up a new aquarium, JBL recommends measuring the pH value daily during the first week.
