Collection: thermographer

A thermograph (from ancient Greek: θερμός thermós "warm, hot" and γράφειν gráphein "to write") is a measuring device for detecting and recording temperature over a continuous period of time. It is therefore a recording thermometer that controls a recording arm based on its specific input measurement method. This arm, in turn, has a writing tip at its tip, which transfers the temperature change to a rotating paper drum, thus graphically displaying it. The recording time is determined by the rotation speed of the paper drum.
