I have almost the same station, it is the analog version no digital readout. My dial is calibrated to read temp in degrees, it goes from 35 to 85 and that corresponds to 350 degrees to 850 degrees. I really like this station, it heats up very quickly, regulated heat very well and I really like how it will turn itself off after 30 minutes of no use. I would thing your display would give you temperature.
