An artwork about climate

This thermo-hygrometer belonged to the Museum of Modern Art
Arnhem. It keeps track of temperature and humidity and was used
to monitor the atmosphere inside the museum so the artworks
could be displayed under perfect conditions.
A sticker on the device shows it was last serviced in 2002. 
I recontextualised this  instrument by putting it outside. It is now monitoring
the state of the atmosphere outside of the museum.
