4330/P Polarograph
History, still contemporary
Model 4330/P is the historical polarograph by AMEL, developed to be used with the built-in mercury valve that can be operated both as Hanging Drop Mercury Electrode or Dropping Mercury Electrode. Thanks to the constantly updated circuitry, detection limits can be pushed below the ppb level.
Model 4330/P is fully controlled via VApeak software.
