摘要
1. Arrangement for determining the freezing point of a liquid situated on a roadway or taken from the roadway, having a cooling device and an arrangement for measuring the temperature of the liquid, which arrangement is connected to an evaluating device for ascertaining and indicating the freezing point of the liquid, characterized in that a heat-conductive plate (6) is heat-conductively connected to the cooling device (9, 10), that there is a recess (7) in the central region of the heat-conductive plate (6), that a single temperature sensor (8) is embedded in the recess (7) by means of a heat-insulating compound (13), and that the evaluating device comprises means (25, 26, 27, 28) for ascertaining and indicating the freezing point of the liquid as a function of the temperature gradient derived from a series of periodic temperature measurements.
