The Model 4330 Voltammetric Analyzer is a combination of three electrochemical instruments in one.


Thanks to the evolution of electronics and firmware, Amel have been able to combine all modern voltammetric techniques with Potentiometric Stripping analysis (PSA) and pH measurement.

Trace analysis of heavy metals and organic compounds down to ppb (ug/L) levels will easily be
accomplished by the most appropriate technique  and electrode. The integrated cell stand offers
unrivaled versatility, thanks to the wide choice of batch/flow cells and electrodes, from classical
hanging mercury drop and solid electrodes to modern rotating disk and screen printed

Automatic quantitative analysis is then made easy by integration with an Amel 235 Automatic
Dispenser. This combination will allow you to perform routine analysis by a simple button touch
as well as research work on the same instrument.
