: You will need an external heater to superheat the vapor past the saturation point. This must be done in the absence of liquid. There are commercially available electric superheaters that you can purchase, but they are costly.
Yes, now I design the external heater by myself, but the outlet temperature is not stable. And can you tell me how to measure the temperature under such a low pressure? By the way, what is the rough price for that kind of electric superheater? can you tell me some website or company names?
