A reflectance meter for use in a blood glucose tester for measuring the colour change of test strips, treated with blood to be tested. The reflectance meter comprises a strip gate (7) for receiving and holding a treated strip in position. Light from a lamp source (8) is reflected from the strip and sensed by a light sensitive device (9), the output of which is connected to an electronic measuring circuit (55) which determines blood glucose level from the intensity of reflected light. The measured level is displayed by an analogue (14), digital (43), mechanical or thermal display. The strip gates can be coded (48) in accordance with the particular strip variety used. |
