A thermochromic solution of a Cobalt salt can be used as a temperature sensor,since its optical absorption spectrum is strong modified by temperature variations.A thermometer can be realized making use of fiber optics for light transmission to and from the sensor.Such device has been set up and tested in the laboratory:technical data are here presented and pratical measurements and results are then discussed.
