DEFINITION

Classification: 204/406

With significant electrical circuitry or nominal computer device:

(under subclass 400) Apparatus in which the measuring electrode is operable connected to a claimed arrangement of electrical elements or is claimed as connected to a computer.

(1) Note. This subclass is intended to provide for documents which claim an electrochemical sensor in combination with a circuit other than a mere recital of a current or potential measuring means, i.e., claim language like "analysis means for measuring an electrical potential developed" is not provided for here.
