Model 761 Capacitance Manometer (CDG)
Brand: Setra Systems, IncThe Model 761 is Setra’s low cost absolute capacitance manometer designed for semi-conductor, petrochemical, pharmaceutical/process and industrial vacuum markets.
The 761’s new high frequency electronics design is fully RoHS compliant and yields extremely low noise, while maintaining the fast response time required for today’s critical control applications.
External noise rejection, fast warm up, resistance to environmental effects, and quick return to zero are unmatched by competing models costing twice as much.
Features- Wide compensated temperature range
- Extremely low noise
- Outstanding long term stability
- Fast Response time for control applications
