Abstract

A fluid sampling nozzle is spatially fixed, and adapted to be supplied by fluid to be sampled. A nearby actuating switch, manipulated by the operator, energizes a sequence of sampling, cleaning, and drying steps. In particular, once fluid is withdrawn, the sample is removed. A waste removal sink pivots to a point beneath the nozzle, and in a series of motions by a probe washer assembly, the nozzle is successively washed, inside and out. The apparatus is then returned to its initial position, ready for successive sampling operations.
