Thermograph 525 mechanisch

A thermograph is a measuring device for recording and recording the temperature in a continuous, temporal course. It is therefore a registered thermometer, which controls a writing arm via its specific input measuring method. This, in turn, has a writing head at its tip, with which it transmits the course of the temperature to a rotating paper drum and thus graphically depicts it. The period of registration is determined by the rotational speed of the paper drum.
