It helps if you have a hygrometer instead of just a thermometer. The hygrometer also senses the humidity. The best ones are air-sensing.
They are like the one used by parrot breeders and in units called "animal intensive care units. Bonaire makes some nice ones, as do some other companies. Make sure you ask to find out if they are air-sensing " types.

A dial thermometer that you can calibrate is best.
