In this paper we present the results of field tests of a remote spectrofluorimeter designed for detection and analysis of oil spills on water surface. They have been obtained during the summer expedition along Upper Volga onboard "Il'ya Repin" ship. The construction of the device and its operational algorithm are described. Making field measurements we took into account large extent of the measurement path. The recorded signals of the fluorescence intensity and decay time are presented in the paper for two cases of oil spills detected. A fragment of the data summary for a 200 km path near Yaroslavl city is also presented. It is shown in the paper that waters investigated have high background level of fluorescence what makes it necessary to improve essentially the fluorimeter construction.
