ABSTRACT:
Impedance measurements from an array of cells containing microorganisms whose growth or multiplication are to be measured in terms of the impedance, utilizes electrodes which can be introduced into the cells and have contact pieces engageable by one or more probes of a measuring head displaceable by an x, y carriage system into alignment with the successive contact pieces. The system avoids the need for voluminous conductor arrangements and multiplexing systems.
