Brooks Instrument SLA5800 Digital Thermal Mass Flow Controller
About this part
SLA5850S1BAB1B2A1 is a configured Brooks SLA5850 / SLA5800 Series elastomer-sealed digital thermal mass flow controller identifier. Brooks SLA5800 documentation covers SLA5850, SLA5851, and SLA5853 controllers plus related SLA5860-series meters; exact gas, range, process connection, valve package, seals, and communication option remain configured-unit details that should be verified from the unit label
Configurations vary. Verify the exact unit before choosing a replacement.
