Penning Gauge
(10⁻² - 1x10⁻⁹ mbar)


Edwards Passive Penning Gauges provide accurate measurement over the vacuum
range of 1 x 10-2 to 1 x 10-9 mbar. These gauges have proved to be rugged and reliable in a wide range of applications, ranging from scientific instruments to industrial processes, or wherever the use of an active gauge is not possible. There are four model available CPG35K-NW25, CPG35K-NW40, CPG35K-DN40CF and CPG35KB-DN40CF. These passive sensors use cold cathode ionization technology according to Penning. 

Features and benefits
• Rugged
• Insensitive to air inrushes and vibrations
• Easy disassembly and cleaning of the measurement system
• Exchangeable cathode plate
• Improved ignition characteristic through titanium cathodes
