Gemini™ ATM to Ultra-High Vacuum Gauge

 

The INFICON Gemini Inverted Magnetron Vacuum Gauge is the workhorse for all vacuum measurement applications (pending). Gemini combines two sensor systems into one small device to measure from atmosphere to 1x10 – 9 mbar. The patented ultra-low magnetic stray field design opens up a whole new range of applications. A unique interchangeable dual chamber sensor unit avoids cleaning cycles and reduces maintenance, making Gemini the most robust and economical vacuum gauge of its kind.

 

Gemini Cold Cathode and combination comes with fully integrated digital electronics, providing ultimate flexibility for system integration. Cold cathode and Pirani combination option provides seamless transition, reliability, practicality and flexibility across wide ranging applications.

 

MPG500 series represents the latest Technology to act as direct replacement for Cold Cathode or Penning Transmitters of the  PTR 90 / PTR 225 (analog Versions) series.
