Pressure
Recording Instruments

Barograph

This instrument is used to measure and record the atmospheric air pressure. The recording is carried out by means of a hand wound clock work drum mechanism acc. to DIN 8300 and DIN 58658 (3.0800... ; 3.0804...) or with a Quartz clock work ( 3.0815...).The on-site elevation can be set by means of an adjusting screw. Delivery includes a set of recording charts (100 sheets).
