A thermometer will completely drop when in a vacuum as there is nothing in a vacuum, so there will be no energy. A thermometer measures heat energy around it. You may find it'll measure the heat energy that it has itself.
In a vacuum, a thermometer cannot measure temperature via convection heating. Hot air or hot gas can't heat up the bulb or bimetal strip or whatever it is that responds to the heat to make the device work. It will measure some heat because infrared (and other electromagnetic) radiation can warm the device. Depending on the circumstances, it will give some kind of reading, but as to what that reading is, we cannot know without knowing what is in or around the vacuum. Even in deep space there is cosmic background radiation everywhere and the temperature is about 3 K, or −270 °C (−454.00 °F).

Is the thermometer reading the temperature of the vacuum at the Moon's surface?
No. The thermometer measures the temperature of mass or material. Concerning the moon, a thermometer could measure the temperature of dust or rock on the surface. If it were not in contact with the surface, and the sun shone on it, the thermometer would read the temperature to which the sun heated it. If it were shielded from the sun, then the thermometer would read the temperature of space ... about 3 K, or darn near absolute zero.
