  ABDNP201551a01.JPG - Negretti & Zambra: Barograph This fine instrument is designed to record small changes in barometric pressure in laboratory situations where pressure is important.  5 inches (127 mm) of travel of the pen covers pressure changes of 30 mb (30 hPa).  The chart centre can be altered within the range 965 mb - 1025 mb to accommodate large changes in atmospheric pressure. Our collection also contains more conventional barographs, and thermographs.
