MAG084 & MAG086

The gauge head MAG084 is a unique magnetic field resistant inverted magnetron cold cathode gauge designed to operate with the Vacuum Gauge Controller VGC094. Its special design, fitting a double ionization chamber principle, allows vacuum measurement in the pressure range from 1×10^-8 to 5×10^-3  mbar even in presence of strong external magnetic fields. 

Thanks to an all-metal design, NdFeB rare earth magnets, the optimised and closed magnetic circuit and the magnetic shielding enclosure, MAG084 is the answer for all special Fusion and R&D applications requiring the highest performance, including magnetic field immunity. 

MAG084 has a bake-out temperature up to 230 °C and ionizing radiation resistance up to 10⁷ Gy. The gauge head has an ignition aid mounted on the anode (reducing the cold cathode ignition time at low pressure) and can be easily disassembled and cleaned, allowing long term use with minimal downtime.
