1. A method for measuring and adjusting the temperature of ice of artificial ice rinks, in which water is frozen to ice with the aid of refrigerating channels disposed in the rink and in which refrigerant is passed through the refrigerating channels by means of a refrigerating system, and in which the temperature of the ice is adjusted by adjusting the refrigerating effect of the refrigerating system, characterized by measuring the surface temperature of the ice with the aid of at least one sensor which functions to measure infrared radiation from the surface ice, and by processing the signals produced by said sensor in a control unit which controls the refrigerating system in a manner to bring the surface ice to a predetermined temperature;

  • and by calibrating the sensor in conjunction with rinsing or washing the rink with water, the water being assumed to take a temperature of 0°

    C. after a short transition period.
