Abstract
An electronic device for analyzing an aqueous solution may comprise a housing, one or more measurement circuits and a control circuit all arranged inside the housing. The housing may be configured to receive a test element. The one or more measurement circuits may be configured to produce one or more corresponding sets of measurement signals relating to an aqueous solution received on the test element. The control circuit may include a memory having instructions stored therein that are executable by the control circuit to process the one or more sets of measurement signals to determine one or more corresponding characteristics of the aqueous solution.
