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

Full range gauge combining Bayard-Alpert and Pirani technologies provides wide measurement range from 3.8 x 10^-10 Torr to atmosphere (5 x 10^-10 to 1013 mbar)
Pirani interlock protects Bayard-Alpert sensor from premature burnout and contamination effects from high-pressure operation
Long-life yttrium oxide-coated iridium filament brings a rugged design for a wide-range of applications
Setpoint control
LCD display option allows monitoring of pressure readings easily
Profibus communication option facilitates simplified network integration
Replacement sensors are available
The 720 is a single filament version and the 730 is a dual-filament version
Used in a wide range of applications from industrial coating and semiconductor processing to research and laboratory environments
