Definition
Set of one or more devices, including any reagent and supply, assembled and adapted to give information used to generate examined values from a nominal property value set.

Note
A human eye may be an essential element of an examining system.

Examples
1) Selective culture medium for the identification of Candida albicans in a biological fluid.
2) Chromatograph and mass spectrometer for the identification of mass/charge ratios of molecules.
3) Instrument used for running a polymerase chain reaction (PCR) followed by restriction fragment length polymorphism (RFLP) for the identification of a genotype.
