Vérification de notre eau potable avec Cobra4

Numéro d´article: P1520062

Principle

This experiment shows how much the quality of drinking water of various locations in the same region can vary. The comparison of tap water with bottled mineral water and distilled water leads to surprising results.

Benefits

  • Experiment is part of an experiment set with numerous experiments in ecology
  • Universal handheld measurement device can also be used for other measurement parameters relevant in ecology, biology and chemistry
  • Outdoors measurement possible, for mobile use
  • Graphical display of measurement data
  • Data can be saved on SD memory card
  • All data can be transferred onto a computer for data analysis
  • Data analysis software can be freely distributed

Tasks

  • Measurement and comparision of the conductivity values of drinking water samples from the water tap of different locations
  • Comparison with bottled drinking water
  • Discussion of the causes of the conductivity values of the water samples and why they are different

What you can learn about

  • Water quality
  • Ion content of water
  • Salinity
