Solute concentration measurement apparatus comprises a container (1) for a solution together with an ultrasonic transmitter (2) and receiver (3). A signal from the transmitter (2) passes through the solution to be detected by the receiver (3). A clock (5) and microprocessor (6) determine the speed of sound in the solution and hence the concentration of solute present.
