Abstract

The hand-held photometer for measurements on fluids is designed for operation with different fluids without the need for additional appts. or switching operations. The photometer housing has two windows (10f)(10ff) showing two separate scales. The scales are adjusted by means of a thumbwheel at the side of the case (20). Each scale has an associated cursor mark (48) bearing an indication "haemoglobin" or "erythrocyte". The meter is first zeroed by rotating the thumbwheel to an end position and by operating switches (18)(44) and observing the needle (38a) at the top of the instrument. A cell of the test fluid is placed in the compartment (50) on the face of the case and the reading taken from the appropriate scale. The different scales may be coded by means of different colours corresponding to colours on the test cells or phials.
