The traceability of the measured temperature can be ensured by using it in combination with a calibrated thermometer (thermocouple/RTD).
Product under calibration
Temperature indicator that digitally displays temperature by thermocouple and RTD input (portable temperature indicator, temperature controller, recorder, etc.)
