Marine barograph with digital display

Barograph for long term recording of the air pressure

Thanks to a consequent usage of modern technologies (Micro processor...) the Meteograph combines the advantages of mechanic and electronic barographs. The analogue pressure sensor signal is amplified in a signal processor, digitalized and passed on to the micro computer. There the air pressure is calculated. A very accurate temperature - and pressure indication is guaranteed with the calculated correction of the linearity- and temperature deviation. 

With the tip of the scriber the fluctuating air pressure is engraved on the back of waxed paper. The resulting mark is immediately visible on the display. The continuous, rectilinear record is therefore produced without ink or felt tip markers. (No dirtying of fingers or the instrument, you don´t need  to replace worn parts). The scriber is behind the roll, so the paper roll replacement is as easy as replacing a film in a camera. One paper roll is sufficient for one year´s operation.
