Analytical complex Ecotest-VA VDE
Analytical complex Ecotest-VA VDE. Ecotest-VA VDE is designed to measure heavy metals and toxic components. The analyzer consists of an electrochemical cell, a measuring transducer and an IBM compatible personal computer with an installed software package. Design features allow you to automate the processes of isolating, identifying and measuring the amplitude of voltammogram peaks, as well as processing measurement information and calculating the mass concentrations of ions of chemical elements and substances of the analyzed medium. The measuring transducer is connected to a PC using a connecting cable via the RS-232C interface. It is equipped with a built-in microprocessor. Compact budget complex with rotating carbon-sitall disc electrodes and special electrodes for measuring heavy metals and toxic components: Zn, Cd, Pb, Cu, Bi, Ni, Co in drinking, natural, waste water, food products, soils; Zn, Cd, Pb, Cu - in the air of the working area; in alcoholic products, As - in drinking water, natural water, waste water, food products according to GOST 31628-2012, MUK 4.1.1510-03, in alcoholic products according to GOST R51823-2001, Fe - in alcoholic products GOST R51823-2001. VDEs are small-sized high-speed rotating electrodes. Compactness and low weight expand the possibilities of its use, not only in laboratory conditions, but also in field conditions, including in mobile laboratories.
