ELECTROCHEMICAL SENSORS AND THE WORKING ELECTRODES FOR "ECOTEST-VA"

Electrochemical sensors
The stationary electrochemical sensor  EM-04

The stationary electrochemical sensor "EM-04"

    The stationary electrochemical sensors "EM-04" and "AKV-07" with the rotating disc electrode are characterized as follows:
  • microprocessor-stabilized and finely ajustible rate of rotation of the disc electrode
  • complete compatibility with the analyzer "Ecotest-VA"
  • the possibility to be equipped with carbon-cytallic, gold (to determine Hg, As and Te) and platinum disc electrodes
  • a wide range of the analytes: Zn, Cd, Pb, Cu, As, Hg, Ni, Bi etc
  • the hydrodynamic conditions in them allow to perform the analysis of samples for the contents of heavy metals, arsenic, mercury, nickel, bismuth etc in a wide range of objects in the laboratory conditions during the minimal time with the maximal comfort for the operator
The stationary electrochemical sensor AKV-07

The stationary electrochemical sensor "AKV-07"

The analyzer "Ecotest-VA" with the stationary electrochemical sensors provides the possibility to determuine Zn, Cd, Pb, Cu in the food products according to Russian National Standard GOST R 51301-99; and Zn, Cd, Pb, Cu, As, Hg, Fe, sulfur dioxide in the alcohol-containing drinks and in the raw materials for their production according to Russian National Standard GOST R 51823-2001 (act from 01.01.03).
The shipping kits of "Ecotest-VA" with rotating-disc electrode stands -04 or -07 provide the possibility to measure zink, cadmium, lead and copper and also nickel,cobalt and bismuth with the following characteristics.
