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 with extra equipment, available as accessories and for which room has been reserved in the case:

• depth of transparency (measured using a Secchi disc or a Lux meter with immersion probe)
• water profiles (measurement down to 10 m depth using a water scoop)

The methods are mainly chemico-physical determinations acc. to BACH. They allow an objective assessment of the water quality and are referred to by the Scottish and American Environmental Authorities, as well as those of some German Federal States, in their reports on water quality. The chemico-physical examination methods always give momentary values and so allow measurements of variation over time (daily and seasonal variations) as well as at different positions (e.g.pollution by influents). Added meaning is given by supplementing these methods with biological methods, which aim at the documentation of long-term changes in the condition of the body of water.
