Admiral Instruments features a variety of corrosion cells sourced from Zahner Scientific Instruments in Germany. The KMZ3 corrosion measuring cell is a triple electrode non-water-jacketed cell for standard electrochemical measurements. A temperature-controllable variant is available, the KMZ5 corrosion measuring cell, which has a triple electrode water-jacket cell for standard electrochemical measurements with a cell container suitable for connection to constant temperature circulators. The AMZ60 Flat Sample Corrosion Cell specializes for samples in a flat plate configuration.
Some application fields include:
Each KMZ3 corrosion cell comes with: specimen holder (WE), counter electrode, reference electrode (Calomel), liquid junction tube, intermediate vessel, gas in- and outlet. The KMZ5 includes the following extras: reference electrode (Ag/AgCl), thermometer, glass stirrer.
