Product review (3 stars): This inexpensive device does the job
Although  the box just says "thermometer," this does display relative humidity as well.  The temperature is displayed in C rather than F, as it says in the description.  Since I already have thermometers, this didn't matter to me.  The display on mine was exactly as pictured -- humidity in large type, temperature in degrees C in small type.  Temperature and humidity seem to be accurate.
