EE I'd say.

One name would be an "environmental chamber". Depending on how hot or how
cold you want to go, a Peltier effect controlled refrigerator as sold in
many US stores may do the trick. The Peltier device can either heat or cool
(by reversing polarity). Typical cool boxes have a 50 watt Peltier and a fan
and are large enough to take 4 to 6 large soft drink bottles.

A controller can be made that will seamlessly switch the Peltier device from
heating to cooling as required.
