This is realy the top of the modern styled barometers.
The basic is a 20mm thick piece of sanblasted glass with a facet.
The hygrometer is on a second level again mounted on glass.
Between the wall and the glass and between the barometer and the hygrometer there are massive chrome holders.
The scale of a contrabarometer is 10 x larger then the scale of a Torricelli barometer, so it is very easy to read. One of the absolute bestsellers in our collection.
