<p>A test system for the semi-automatic analysis of chemical constituents in a test fluid which comprises test devices having test reagents and code means associated therewith and an instrument which receives the test devices and is programmed by the device code means for automatically reading the particular test reagents associated with the particular test device being used. Preferably the test reagents are in a dry form, immobilized in or on a carrier member which upon contact with the test fluid can be manually presented to the instrument. Another preferable embodiment of the present device comprises the use of the code means to calibrate the instrument each time a test device is introduced thereto.</p> |
