FRG-720/730 Pirani Bayard-Alpert Gauge

 

The FRG-720 and FRG-730 combine Agilent's Pirani and Bayard-Alpert sensor into a single compact design that provides measuring capability from 5 x 10-10 mbar to atmosphere (3.8 x 10-10 Torr to atmosphere). Combining these two technologies into a single unit reduces complexity and integration challenges while protecting the Bayard-Alpert sensor from premature burnout.
