Brooks Instrument SLA5800 Digital Thermal Mass Flow Controller
About this part
SLA5850S1EAB1B1A1 is a configured Brooks Instrument 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, full-scale range, connection, seal package, valve state, and communication options remain configured-unit details. Sonisys auction history and exact listing evidence show this configured code appearing with 1/4 VCR, 15-pin units and gas/range variants including AIR 10 SLM, H2 10 SLM, AR 5 SLM, O2 10 SLM, and O2 20 SLM
Configurations vary. Verify the exact unit before choosing a replacement.
