3. Construction
3.1. Front panel of meter
Meter is made up of electric unit and electrode system. Electrode
system is made up of ion selective electrode, conductive electrode
DO electrode and temperature measurement electrode.
When it is ex-factory, ion measurement electrode is equipped with
pH combination electrode. Conductive measurement electrode is
equipped with DJS-1C-F platinum black electrode, DO
measurement electrode is equipped with DO-958-S-F dissolved
oxygen electrode. (as per packing list. If you want to measure
other ion, you need to buy suitable ion selective electrode
according to practical needs. The same, you can also select other
conductive electrode with different constant. )
