CWZ series: Deadweight Pressure Vacuum Tester PRODUCT DESCRIPTION: The latest piston-type pressure vacuum gauge verification discipline of China came into force in 30, January 2010. The implement of this discipline means the new gauge will replace the previous JJG236-1994 and JJG239-1994. The measurement range of this discipline is -0.1 0.6MPa. Also, the technical requirements are improved a lot.
