The factory for precision mechanic was founded in 1945 by aircraft engineer Kurt Fischer in a little village in the ore mountains named Drebach. Since that time experienced staff members have designed and created excellent instruments for measuring weather and climate. Precise instruments, well balanced up to the detail.

Our trade and aim is to combine solidness and best craftsmanship in precision engineering. Therefore we create instruments that are stable in value and give our products a reliability that lasts for generations.

The careful use of all resources and the use of environmentally friendly production processes are sustainable production the way we see ourselves.

Galileo Thermometers
Based on a discovery by Galileo Galilei (1564-1642)

History
Searching for a way to measure exact temperature, Galileo discovered this fascinating method. He placed several exactly weighted balls in a cylinder filled with a certain liquid. He found that the balls rose or fell according to the temperature. By this method, he was able to do determine the current temperature.

How it works
This thermometer works on principle that the density of a liquid changes as temperature varies.
Each of the glass balls is exactly weighted by partially filling them with liquid. When the temperature rises, the liquid in the glass cylinder becomes less dense, and heavier balls sink slowly to the bottom.

How to read
Place thermometer on a flat surface.
The lowest temperature ball within the group at the top of the cylinder tells the current temperature.
