The paper is about calibration of contact sensors for measuring temperature of solids surface. The paper describes process of idea development, design and make of prototype apparatus for calibration of contact sensors in temperature range from +50 °C to +600 °C is described. The apparatus consists of two separate and integrated systems for heating. The test results are given in the form gained by measurement determined characterization of the relevant parameters of the apparatus, according to the protocol for the validation of the method. The significant improvements and innovative approach are confirmed and extending of the temperature range up to 600 °C is provided. These innovations are related to the way of heating the reference body to a set temperature calibration point. The innovations are also seen in a way to ensure long-term uniformity of temperature profile and stability of the temperature of the reference surface with standard deviations less than 0,01 °C to 0,05 °C, based on values read-out during 180 min in the entire calibration range. The specified individual and summary contributions of measurement uncertainty of the apparatus for all calibration points are specified in the end.
