3.1 Electrodes
MME
MME stands for Multi-Mode Electrode and is the working elec-
trode commonly used in the 757 VA Computrace Stand. It com-
bines the most important polarographic and voltammetric mer-
cury electrodes in a single construction:
DME
Dropping mercury electrode
SMDE Static mercury drop electrode
HMDE Hanging mercury drop electrode
For installation and maintenance of the Multi-Mode Electrode, see
Hardware Manual.
DME
DME is an electrode mode of the Multi-Mode Electrode and
stands for
Dropping Mercury Electrode. It is the classical mer-
cury electrode where the mercury flows out freely from the glass
capillary until the mercury drop is knocked off by a tapping
mechanism after each
Voltage step time set in the measurement
mode.
