Introduction
The authenticity of atmospheric and vacuum pressure is evident since period of Galileo and hypotheses and experiments related to those subjects was considered in ancient times. This period of 17th century was crucial for the vacuum science as for many other scientific fields. Many researchers worked on the same theory including, Otto von Guericke, Robert Boyle and Blaise Pascal (Calcatelli 2013). The rising demands on accuracy in result require constant calibration. According to Rucki, Barisic & Varga (2010) , metrological properties of the measuring tools, is significant. Sometimes it appears difficult to calibrate parameters of pressure gauge, because its gauging ...
