VORRICHTUNG ZUR BESTIMMUNG UND/ODER ÜBERWACHUNG DES PH-WERTES EINES MEDIUMS |
摘要 |
The invention relates to a device for determining and/or monitoring the pH of a medium in a container by measuring the potential gradient between a pH half-cell (3) and a reference half-cell (4). According to the invention, the device is provided with a screen (12) made of an electroconductive material. Said screen (12) is embodied in such a manner and/or is arranged relative to the pH half-cell (3) and the reference half-cell (4) in such a way that outer parasitic potentials superimpose the two half-cells (3, 4) in a substantially equivalent manner and in the same sense. |
