Abstract

A measuring arrangement for registering a measured variable representing concentration of an analyte in a measured medium, includes: a first electrode modified with a redox active substance, a second electrode, and a measuring circuit, which comprises a voltage source for applying at least one predetermined voltage between the first electrode and a reference, and an apparatus for registering electrical current flowing, in such case, between the first electrode and the second electrode or for registering a variable correlated with the electrical current flowing between the first electrode and the second electrode, wherein the second electrode is modified with the same redox active substance as the first electrode.
