Abstract
Electrical voltage indicating device for use in the low-voltage range, characterized in that it comprises at least one electrochemiluminescence cell containing at least two electrodes immersed in an electrolyte containing at least one electrochemical substance whose luminescent excitation threshold value corresponds to the value of a voltage to be monitored. The use of several such substances each having a different luminescent excitation threshold in the same cell or of several cells, each with a substance of different excitation threshold value connected in parallel makes it possible to monitor several different voltage values with the device.
