A thermocouple type electronic thermometer which includes automatic adjustment of the signal conditioning circuitry to be compatible with the calibration curve of the thermocouple in use. A plurality of thermocouples are stored in a container which has conductive markings imprinted thereon which are a representation of the voltage/temperature characteristic of the thermocouples in the container. The markings are detected by contacts in the thermometer case, and the calibration of the instrument is altered so that the display will be an accurate indication of the temperature being measured. The principle is applicable to the measurement of other physical phenomena. The instrument is automatically switched on when a thermocouple probe is connected, and switched off when the probe is disconnected.
