An apparatus for measuring characteristics of a liquid including a channel through which, during operation, the liquid flows and a plurality of sensors for measuring characteristics of the liquid as it flows through the channel. The cross-sectional shape of the channel varies along its length, but the cross-sectional area of the channel is substantially constant so that, during operation, liquid flows through the channel at a substantially uniform speed. The sensors include an ultra-violet sensor and an infra-red sensor, each having a source and a detector of electromagnetic radiation arranged along an axis transverse to the channel. The axes of the two sensors are transverse to each other.

[ What is claimed is:] [1.] An apparatus for measuring characteristics of a liquid, the apparatus including a channel through which, during operation, the liquid flows and a plurality of sensors for measuring characteristics of the liquid as it flows through the channel, the internal cross-sectional shape of the channel varying to accommodate a plurality of sensors located within the channel for measuring respective characteristics of the liquid, the internal cross-sectional area of the channel being substantially constant so that, during operation, liquid flows through the channel at a substantially uniform speed, the sensors including a first optical sensor which comprises a source of electromagnetic radiation and a detector of electromagnetic radiation and which is arranged along a first axis transverse to the channel and a second optical sensor which comprises a source of electromagnetic radiation and a detector of electromagnetic radiation and which is arranged along a second axis transverse to the channel and transverse to the first axis, the optical path length through the liquid of the first optical sensor being longer than the optical path length through the liquid of the second optical sensor.
