FEATURES
· 2-way normally closed
· Applications where control is critical
or flow is required below 600 sccm
· Provides computer-automated
calibrations and full calibration
traceability
· Uses either DC current or pulse width
modulation with closed loop feedback
to deliver optimal system performance
· Maintains ideal flow through thermal
compensation
· Highly repeatable
· Oxygen and analytically clean
