Brooks Instrument SLA5850 Digital Mass Flow Controller
About this part
SLA5850D1BAB1A2A1 is a configured Brooks Instrument SLA5850 digital thermal mass flow controller in the SLA5800 Series. Official SLA5800 documentation identifies SLA5850 as a mass flow controller platform with configurable gas, full-scale flow, valve, elastomer seal package, and digital I/O options. Stored Sonisys auction records for this exact identifier include Delta Smart II wording and 500 SCCM flow context; at least one listing records has described O2 1 SLPM context, so the physical unit label remains authoritative for the exact calibration
Unit-specific configuration
Historical listing records identify this part as 500 SCCM. Exact gas, range, fittings, valve configuration, and communication interface must be verified from the physical unit label.
Configurations vary. Verify the exact unit before choosing a replacement.

Key Facts
Specifications
| Device type | Elastomer-sealed digital thermal mass flow controller |
| Series family | Brooks SLA5800 Series elastomer-sealed digital thermal mass flow controllers and meters |
| Model role | SLA5850 is the lower-flow SLA5800 Series controller platform; the data sheet lists any full-scale range from 0-3 ccm to 0-30 lpm N2 equivalent, with up to 0-50 lpm N2 equivalent using the coplanar valve option |
| Configured-unit rule | Gas, full-scale range, process connections, seals, valve state, power, and digital communications vary by configured code |
| Series accuracy context | SLA5800 data-sheet accuracy is listed as +/-1.0% of rate from 20-100% full scale plus +/-0.2% full scale below 20% full scale up to 1100 lpm N2 equivalent |
| Repeatability | SLA5800 data sheet lists repeatability as +/-0.20% of rate |
| Response time | SLA5800 data sheet lists less than 1 second to within +/-2% full scale for a 0-100% command step through 100 lpm N2 equivalent, and less than 3 seconds above 100 lpm through 2500 lpm |
| Digital platform | SLA5800 devices support analog and digital I/O options depending on configuration |
| Gas/range programmability | The SLA5800 platform supports storage of selectable calibration curves and MultiFlo-related gas/range flexibility on applicable configurations |
| Application domain | Advanced gas handling, production, laboratory, analytical, fuel-cell, life-science, and process gas control applications |
| Stored auction gas/range combinations | Stored Sonisys titles include 500 SCCM context for SLA5850D1BAB1A2A1; listing evidence has also shown O2 1 SLPM context |
