Hygrograph

 A Hygrograph is a meteorological instrument for monitoring and recording of the humidity in a continuous, time course. Therefore, there is a registering hygrometer which controls a writing arm about its specific input measurement method. This in turn has a write essay with which he transmits the history Humidity or the corresponding moisture measurement on a rotating drum paper and thus represents graphically at its peak. Hair hygrometer case form the most widely used input methods of measurement and account for the variation of the relative humidity. The period of registration is determined by the rotational speed of the paper drum.

The main features of Hygrographs 252 with display are:

• Can also be used below 0 ° C
• fluctuations in the relt.. humidity there is a self-regeneration of natural hair
• low hysteresis
• high rate of reaction
• good handling
• high reliability
• easy handling
• mechanical and electronic drive
