The disclosure concerns both a method and an apparatus for rating a thermometer probe, wherein the thermometer probe includes a small thermistor sensing element 20 and a pair of conductors 14, 16 connected with the thermistor contacts and being supported upon a substrate 12. With the thermistor 20 held at a particular temperature, the electrical resistance of the thermometer probe is measured and the difference between the resistance of that probe and a standard resistance is fed to a computer which operates a laser to encode a machine-readable character on the probe representative of the difference betweem the measured resistance of the probe and the standard resistance. In use, the probe is inserted in a readout and the readout senses the actual resistance of the thermometer probe which is dependent upon the temperature of the thermistor. An optical reader reads the encoded character on the probe and adjusts the actual sensed resistance for the deviation of the resistance of that probe from the standard resistance, whereby the readout accurately indicates temperature sensed by each thermistor probe.
