The 780 pH meter has an automatic electrode check, which gives
you information about the state and performance of your electrode
at any time.
The stirrer can be controlled directly over the 780 Metrohm
Serial Bus (MSB) interface.
The Unitrode can be purchased in different lengths from 125 mm to 450 mm.
The fixed ground joint diaphragm of the Unitrode stops back diffusion of the sample into the reference chamber of the electrode. The electrolyte solution can not be contaminated with sample.
Practical hints
If the diaphragm of the Unitrode is blocked there is no need to use chemicals in order to clean it. With a soft brush you can remove the impurities which have accumulated on the diaphragm surface.
Do not use an electrode with a ceramic pin diaphragm!
pH measurement in water – quite easy with Metrohm!
