Lead in platinized platinum electrodes used for conductivity measurements at least one of the following conditions applies:

(a) wide-range measurements with a conductivity range covering order of magnitude (e.g. range between 0,1mS/m and 5mS/m) applications for unknown concentrations;

(b) measurements of solutions where an accuracy of +/– 1% of the and where high corrosion resistance of the electrode are required the following:

(i) solutions with an acidity <pH 1;

(ii) solutions with an alkalinity >pH 13;

(iii) corrosive solutions containing halogen gas;
