FRG-700/702 Pirani Inverted Magnetron Gauge

The Agilent FRG-700 Gauge is a full range gauge that provides two measuring technologies in a single, compact and economical package to measure process and base pressure from 5 x 10-9 mbar to atmosphere (3.8 x 10-9 Torr to atmosphere). The single, compact unit with one logarithmic analog output signal, significantly reduces the complexity of installation, setup and integration. The benefits are reduced cost and a marked reduction in valuable space requirements. The FRG-702 is the all-metal version of the FRG-700, incorporating a metal-sealed feedthrough. It can be operated at higher temperatures (max. 150º C at flange) than the FRG-700 (max. 55º C at flange).
