Abstract
The liquid to be measured flows through a flow-pipe and bathes the end (1) of a pivoting probe in a spectrophotometric cell (2). One measuring surface (15) of the probe (2) remains immersed in the liquid whose level is advantageously assured by an overflow barrier (19); but when the probe has pivoted, the measuring surface opens onto a duct (23) in which a rinsing liquid flows and leads into the flow-pipe and cleans it. This rinsing is quick and safe and requires no dismounting of the probe. The invention applies in particular to liquids containing radioactive products such as uranium and/or plutonium.
