On the basis of the main unit of EXPERT-001
The registration number in the National standard Commitees of Russia and Ukraine 21068
The instrument aims at the express-measurement (2-8 min) of the mass concentration of oxygen, consumed during the chemical oxidation of the sample (COD) according to the standard procedure accepted in ecology PNDF 14.1:2.19-95.
The principle of the method of the COD measurement is the bichromate oxidation with the direct potentiometry.
    The objects of analysis:
  • drinking, natural, sea and waste water
  • the extracts of soils and bottom sediments
  • the extracts of microbiological, physiological and other media
The set  Expert-001-COD

  • reverce cooler
  • the power supply unit for the heater
  • magnetic stirrer
  • laboratory stand
  • the instruction for the analytical procedure, the operator manual
  • software
  • chemicals (to be ordered separately)
    Particulars of use:
  • express-measurement with a high precision of results
  • more ergonomic than other models
  • there is a possibility to estimate the part of substances with a different ability to get oxidized
  • the possibility to be used as a high-precision pH/ion-meter when equipped with the ion selective electrodes
