5850EM Series Metal Sealed Thermal Mass Flow Controller

Brand: Brooks Instrument

5850EM Series metal sealed mass flow controllers measure and control high-pressure gas flows in ultra-clean environments with a proven stability built on the performance of the widely used 5850E & i Series MFCs. 

Its metal sealed construction and electro-polished wetted surfaces ensure outstanding flow integrity and help improve overall process efficiency by eliminating the need for continuous monitoring and readjustment of gas pressures to provide a stable gas flow.
Features
  • Long-term zero stability of < 0.2% full scale per year
  • < 3 seconds settling time to command changes with negligible overshoot/undershoot
  • Wide flow range – from 3 sccm up to 30,000 slpm
  • High pressure rating - up to 1,500 psi
  • Optional enhanced process internal finish - 5µ inch Ra avg
  • Removable flow sensor
  • Insensitive to mounting attitude
  • Mechanically and electrically compatible with other mass flow controllers
  • TTL compatible "valve off" and purge function
Benefits
  • All-metal flow path enhances gas purity and reduces leaks
  • Proven long-term stability and accuracy across broad process and application range
  • Excellent return on investment due to reliable performance
  • Removable flow sensor eliminates need for continuous monitoring and readjustment of gas pressures
  • Easily installed and serviced with analog only input/outputs
