A compact instrument for measuring the hemoglobin content of whole blood, particularly arranged for the rapid analysis of a minute sample of a patient's blood supplied, immediately after collection, by a doctor in his own office. The instrument is so arranged that it may be fully automated, to make the hemoglobin determination after a blood sample has been delivered to it, and to provide an analysis for the doctor's use within a few minutes. The instrument utilizes a pump which delivers to and mixes with the blood sample in a photometer examination cell, an accurately and continuously measured amount of an aqueous reagent, until the volume of reagent added causes the sample to match photometrically a standard sample. The hemoglobin content is directly shown in appropriate units on a meter or readout device at the completion of a cycle. In the fully automated form of the device, a complete analysis cycle leaves the instrument cleaned out and ready to make another analysis upon reception of another blood sample.
