useMMESemi automatic professional volt ampere polarograph with multi-mode electrode884 Professional VAIt is an easy-to-use analyzer that can use multi-mode electrodesproOrscTRACE GoldPerform trace measurements using voltammetry and polarography. This confirmed Swiss Wanton electrode technology and newly designed constant potential/Constant current meter and external high-performance viva The combination of software has shown new prospects in the field of heavy metal determination. The potentiostat with a certified calibrator automatically flushes for calibration before each measurement to ensure possible high accuracy.

This instrument can also be used for measurement using a rotating disk electrode, for example, with the help of«Cyclic voltammetry dissolution method»（CVS）The«Cyclic pulse voltammetry dissolution method»（CPVS）The chronopotentiometric method（CP）Determine the organic additives in the electroplating solution. With the help of replaceable measuring heads, quick switching between various applications using different electrodes can be achieved.

Two randomly equipped liquid filling units800 DosinoAuxiliary solutions such as electrolytes, buffer solutions, or standard solutions can be automatically added during the measurement process.

use viva Software is used for instrument control, data acquisition, and evaluation.
