It is a bit on the pricey side...but if you go to your local hardware store they have infrared thermometer guns that are in my opinion the most accurate, definitely more accurate than any of the ones sold in pet stores, mercury thermometers are suitable but can be off by a few degrees and proper temperatures are very important for keeping a healthy dragon (as you already know) but also even more important when rehabilitating a sick dragon. For Steve, and even your very own dragon, I think that getting one of those nifty temp guns would be a good fit. I am located in South Florida, here at my local home depot I think they were like at max. $30, I think I went with the brand RYOBI, it has never given me problems and I have had it for about a year. Please consider, as Steve will not eat if he feels the temperature is not adequate for his body to digest properly!
Also, since he is not eating, I would maybe consider going with a nutritional formula like OxBow Carnivore care only because he has gone so long without proper nutrients..and even though uvb and heat exposure needs to be near perfect before even thinking about proper nutrients. Gradually adding this in to his daily rehab regimen might help. Also, it can be mixed with extra water to aid in
hydration since you mentioned he hasn't been taking water as readily today.

Some people would mix with Critical care meant for herbivores, I have never done this due to some of the ingredients, like timothy hay. I just don't know, and have yet to research if that is okay for them so I just use the carni care for now. But maybe someone else will comment on that!
Syringe feed with a syringe from the vet (w/o needle of course :lol: ) or the dropper you have from your school. But syringes are better because you can monitor his daily intake to track any improvement in appetite.
