2-electrode cell type SE 202 with quiver for spare electrodes and a robust field case for the instrument and cell. For checking the purity of water, for measurement in natural waters and for checking ultrapure water in power stations. Can also be used in the ultralow conductivity range, e.g. in the desalination of water using ion exchangers.

4-electrode cell type SE 204 with quiver for spare electrodes and a robust field case for the instrument and cell. For all standard applications, for measurements in salt solutions, acids and bases in high concentrations, and for desalination.

(5 quivers; for storing pH electrodes safe from liquids)
