In a former employment I worked on the development of laboratory furnaces. Testing them on site involved running them up to temperature (1000+ degrees) and monitoring the temperature.
On site at Harwell the customer would pop in from time to time to see how we were doing. He'd look into the furnace and tell us the temperature. He always had it right within a few degrees. Years of practice. He trusted his view more than our thermocouples and Wheatstone bridge.
