Abstract
A device for counting particles comprises a detector arranged to produce an electrical measurement signal in response to the passage of one or more particles, and a comparator arranged to compare the measurement signal with a threshold signal and to increment a counting value when the measurement signal exceeds the threshold signal, characterized in that it furthermore comprises a threshold-adjusting circuit that applies a lowpass filter to the measurement signal, and that is connected to the comparator in order to use the resulting signal as threshold signal.
