It is also called "polarization cell" which is specially designed for corrosion measurements.
Standard cell 5 ports, 500mL
The cell includes: -Specimen holder (effective working area1cm2)* 1 -Graphite rods *2 -Platinum plate electrode (10*10*0.1mm)*2 -Saturated calomel electrode *1 -Salt bridge*1 -F-shape gas inlet & outlet*1
You just need to prepare a round specimen to install in the specimen holder. The cell can be used for one or two counter electrode system The distance between reference electrode and working electrode is very small Another port can be added/ tailored to make it to be a 6-port cell
