Thermograph
A thermograph (from ancient Greek : θερμός thermós “warm, hot” and γράφειν gráphein “write”) is a measuring device for recording and recording the temperature in a continuous, temporal course. It is therefore a recording thermometer that controls a writing arm via its specific input measuring method. This in turn has a writing attachment at its tip, with which it transfers the course of the temperature to a rotating paper drum and thus displays it graphically. The registration period is determined by the speed of rotation of the paper drum.
In meteorology, the air temperature is recorded with thermographs , whereby in weather stations thermographs are usually implemented together with hygrographs in one measuring device, which is referred to in the following as thermohygrograph .
