A membrane osmometer is disclosed comprising a semipermeable membrane having first and second opposing surfaces. Means are provided for receiving and confining a solvent in fluid communication with the first membrane surface. Means also are provided for receiving and confining a solution in fluid communication with the second membrane surface. The osmometer further includes a fluid supply inlet conduit, an outlet conduit, and a distributing valve having at least two positions whereby fluid communication may be established between the conduits and the solvent receiving and confining means with the valve in a first position and between the conduits and the solution receiving and confining means with the valve in the second position. A semiconductor pressure transducer is also provided having a pressure-sensitive surface element in pressure communication with the contents of one of the receiving and confining means.
