Brooks Instrument Smart-Series Digital Mass Flow Controller
About this part
5850S/BC1BA1AA0AA1B1SMART is a configured Brooks Instrument 5850S Smart-Series thermal mass flow controller identifier observed in stored Sonisys auction records. Official Brooks 5800S documentation covers the 5850S controller model in the Smart Mass Flow family, but no verified official Brooks PDF or product page is currently available that names the full configured identifier. Exact gas, full-scale flow, calibration gas, fittings, valve state, input/output option, and seal package should be verified from the physical unit label or calibration paperwork
Configurations vary. Verify the exact unit before choosing a replacement.
