This 5-in-1 water quality tester is an ideal tool for many type of water analysis all in one handy instrument. It has the following parameters.

  • pH - measure the Acidity and Basicity of a solution.
  • EC - measure the Electrical Conductivity of water that is used to help indicate water purity.
  • TDS - indicate the Total Dissolved Solids in a solution that is also an aid in many water analysis procedure.
  • Salinity - measure of the concentration of dissolved salts in water.
  • Temperature - knowing the temperature in water is an essential key factor in water analysis. Temperature influences the rate of chemical and biological reactions.
