The 884 Professional VA semi-automatic professional volt ampere polarograph using MME (multi-mode electrode) is an easy-to-use analyzer that can be used for trace determination by voltammetry and polarography using multi-mode electrode Pro or scTRACE Gold. This has been confirmed with the Swiss Wantong electrode technology, the newly designed constant potential/constant current meter, and the high-performance external connectionvivaThe 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 to measure organic additives in electroplating solutions using rotating disk electrodes, such as cyclic voltammetry stripping method (CVS), cyclic pulse voltammetry stripping method (CPVS), and chronopotentiometry (CP). With the help of replaceable measuring heads, quick switching between various applications using different electrodes can be achieved.

The two randomly equipped 800 Dosino dosing units can automatically add auxiliary solutions such as electrolytes, buffer solutions, or standard solutions during the measurement process.

UsevivaSoftware is used for instrument control, data acquisition, and evaluation.

The semi-automatic professional volt ampere polarograph 884 Professional VA using MME (multi-mode electrode) is supplied with a large number of accessories, including a measuring head for multi-mode electrode pro. Electrode kit andvivaThe license must be ordered separately.
