Are there temperature specifications for the the fume hood? Would it be useful to have an element that measures temperature (perhaps to keep a volatile chemical from flashing)?
Fume hoods typically do not have specific air flow temperature requirements. The fume hood’s goal is to safely remove whatever air is currently in the laboratory, and this air is conditioned before it enters the lab. If the fume hood exhaust temperature is ever required, it is typically measured by a temperature sensor in the exhaust ductwork downstream of the fume hood (and not directly inside of the fume hood).
