PRESSURE MEASUREMENT
• Low pr ( Below 1 mm of Hg)- manometer and low pr gauges• Medium and low ( between 1mm of Hg 1000 atm)- Bourdon
gauge and Diaphragm gauges• Low vacuum and ultra high vacuum( 760 torr to 10 raise to -9
torr and beyond)- McLeod, thermal conductivity and ionisation gauge
• Very high pr (1000 atm and above)- Bourdon gauge,Diaphragm and electrical pr gauges
