Item no.: 30834-88 Function and Applications Eco-Kit “Biological testing of water quality”. The physical, chemical, and bacteriological examination procedures primarily allow an assessment of the momentary water quality. As the variety of species in a body of water decreases with increasing pollution, and the composition of the organism societies thereby changes, the biological determination of
Item no.: 30837-88 Function and Applications This kit allows up to 8 work groups to carry out field examinations of running water and lakes. The following parameters are measured: temperature oxygen content pH-conductivity nitrate, nitrite, phosphate and ammonium content alkalinity (total hardness) The examinations can be extended to further parameters when the kit is supplemented
Item no.: P4100160 Principle These measurements help to quickly and simply introduce the term “heat capacity”. The students learn on which characteristics temperature changes of surfaces depend. As practical example, reference can always be made here to the hot sand at the seaside. Tasks To prepare comparison curves showing the different heat capacities of water
