What is it?

Could you post a picture ?

Sounds like it might be a hydrometer used in wine making to determined the alcoholic strength.

Then again it could very well be a thermometer as described here: http://en.wikipedia.org/wiki/Galileo_Thermometer

I think it is a room temperature thermometer, in Celsius.

Those temps are within the room temperature range: Fahrenheit to Celsius Converter (http://www.wbuf.noaa.gov/tempfc.htm)
