There is a E type thermocouple and K type electronic potentiometer is assembled as below. One day you used this device to detect a very hot metal. If the meter indicated the temperature is 200 degree Celsius, please determine the true temperature of the hot metal. (The room temperature is 25 degree Celsius) K type thermocouple index E type thermocouple index
