Water analysis case
▪
▪ ▪ ▪
The evaluation of the test is made either by comparing the colour of the sample solution with the colour scale supplied or by simply counting the number of drops of reagent added until the colour change in the sample solution occurs The simple handlingallows the tests to be carried out even by untrained people The tests contained in this water laboratory are so sensitive, that they allow the stringent limiting values of the German Drinking Water Regulations to be reached The reagents used are bio-degradable or of no environmental concern
Equipment and technical data Function and Applications For the determination of the quality of bodies of water which are to a great extent unburdened with waste water and of the pollution caused in them by an influx of municipal waste water, or for the monitoring of pond fertilization.

Water test lab for quick analysis
The case contains the complete equipment for the determination of the type of soil, the soil structure, the pH of the soil and its nutrient content, i.e. the nitrogen, phosphate and potassium content available to plants. Benefits ▪ ▪
▪ ▪
The manual contains detailed descriptions of experiments for determining soil characteristics It contains a complete schedule for soil testing, from taking samples to differentiating the various soil types, from the determination of the nutrient content to the calculation of the amount of fertiliser required It also supplies valuable background information All necessary reagents, equipment and accessories are clearly positioned in the case, so that a glance suffices to check that it is complete.
Equipment and technical data Function and Applications This small water laboratory for the most important water parameters contains complete sets of chemicals for the examination of water for: Measuring range: ▪ ▪ ▪ ▪ ▪ ▪
Ammonium 0.05-10.00 mg/l Nitrate 10.00-80.00 mg/l Nitrite 0.02- 1.00 mg/l Phosphate 0.50- 6.00 mg/l Total hardness 1 drop = 1°dH pH 5.00-9.00
