Every product line has a workhorse — our 5850E and 5850i Series thermal mass flow controllers fit the bill. Actively in use for decades in thousands of applications worldwide, they utilize a unique, extremely stable flow sensor to provide the reliable, accurate and repeatable measurement and control that today’s demanding industrial manufacturing processes require.

Features

• Long-term zero stability of <0.2% full scale per year
• Fast flow response to command changes with negligible overshoot/undershoot
• Wide range of flow ratings - from 3 sccm up to 1000 slpm
• High pressure rating - up to 1,500 psi
• Removable flow sensor
• Insensitive to mounting attitude
• Mechanically and electrically compatible with other mass flow controllers
• Electrically activated valve override
• Corrosion-resistant valve

Benefits

• Proven long-term stability and accuracy across broad process and application range
