Abstract
In a measuring device for measuring the concentration of a substance in a liquid applied to the test field of a test strip having two first electrical contacts at its forward end connected to the test field, a conductor plate inside of the device carries a measuring and evaluation circuit and also has formed on it two second electrical contacts which two second electrical contacts, when the forward end of the test strip is inserted into the device through an insertion slot, are brought into contact with the two first contacts on the test strip to connect the test field of the test strip in circuit with the measuring and evaluation circuit of the conductor plate.
