DESCRIPTION

The 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.
