Brooks Instrument SLA5850 Digital Mass Flow Controller
About this part
SLA5850S1EAB1B2A1 is a configured Brooks Instrument SLA5850 digital thermal mass flow controller in the SLA5800 Series. Official Brooks SLA5800 documentation identifies SLA5850 as an elastomer-sealed mass flow controller model, while the full configured code defines options such as RS485 communication context, 1/4 inch VCR mechanical connection, elastomer materials, normally closed valve type, 0-5 V analog I/O, 24 Vdc power, standard response, and safe-area certification. Gas and full-scale calibration remain unit-specific and should be verified from the physical label or calibration records
Unit-specific configuration
Historical listing records identify H2 at 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 general-purpose gas mass flow controllers and meters |
| Model role | The SLA5850 model code family is the SLA5800 Series mass flow controller model for 0.003 to 50 slpm nitrogen-equivalent full-scale flow ranges; the matching meter model is SLA5860 |
| Configured option interpretation | SLA5850S1EAB1B2A1 parses against the Brooks SLA5800 model-code table as standard elastomer series, mass flow controller, body size 0, RS485 digital I/O context, 1/4 inch VCR mechanical connection, Viton O-ring, Viton valve seat, normally closed valve, 0-5 V analog input/output, 24 Vdc power, standard response, and safe-area certification |
| Configured-unit rule | Gas calibration, full-scale range, fitting details, seals, valve/orifice details, communication setup, certification markings, and installed firmware should be verified from the physical unit label and calibration records |
| SLA5850 family flow range context | Brooks SLA5800 data-sheet documentation lists SLA5850/SLA5860-class coverage from 0.003 to 50 slpm nitrogen equivalent; this is family context, not a confirmed calibrated range for every SLA5850S1EAB1B2A1 unit |
| SLA5850 family accuracy context | Brooks SLA5800 data-sheet documentation lists standard SLA5850/SLA5860-class flow accuracy as +/-0.9% of setpoint from 20-100% full scale plus +/-0.18% of full scale below 20% full scale, with 17025-certified options documented separately |
| Repeatability and response context | Brooks SLA5800 data-sheet documentation lists repeatability and reproducibility as 0.20% of setpoint and response time under 1 second for SLA5850/SLA5860-class devices within the documented command-step condition |
| Pressure context | Brooks SLA5800 data-sheet documentation lists SLA5850/SLA5860 standard maximum operating pressure as 1500 psi / 103 bar, with optional higher-pressure configurations depending on model and flow conditions |
| Digital and analog I/O context | The configured S and B code positions indicate RS485 digital I/O context with selectable analog I/O and 0-5 V input/output on the 15-pin D-connector; setup should be verified from the unit configuration |
| Application domain | Advanced gas handling, laboratory, analytical, fuel-cell, life-science, chemical, petrochemical, and process gas control applications |
| Stored and live listing gas/range context | Stored Sonisys titles identify H2 500 SCCM context for this exact identifier, while a live auction listing observed during review identifies N2 500 SMLM context; both are listing observations and not official model-wide specifications |
