Brooks Instrument SLA5800 Series Digital Mass Flow Controller

About this part

SLA5850 is a Brooks Instrument SLA5800 Series elastomer-sealed digital thermal mass flow controller model. Official Brooks documentation identifies SLA5850 as an MFC platform in the SLA5800 family; exact gas, full-scale calibration, fittings, seals, valve behavior, and communication options remain configured-unit details that should be verified from the complete model code, unit label, or calibration record

Unit-specific configuration
Observed configuration

Historical listing records identify this part as AIR 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.

Specifications

Identification
Device typeElastomer-sealed digital thermal mass flow controller
Series familyBrooks SLA5800 Series elastomer-sealed digital thermal mass flow controllers and meters
Model roleBrooks documentation lists SLA5850 as a mass flow controller model; SLA5860 is the corresponding lower-flow mass flow meter model in the same family
Flow
SLA5850 family range contextBrooks SLA5800 data-sheet documentation lists SLA5850/SLA5860 model-class ranges from 0.003 slpm to 30 slpm N2 equivalent, with a coplanar-valve option up to 50 slpm N2 equivalent; the exact configured range is nameplate/calibration dependent
Gas/range programmabilityThe SLA5800 platform supports selectable calibration pages and MultiFlo-related gas/range flexibility on applicable configurations
Configuration
Configured-unit ruleGas, full-scale range, process connections, seals, valve state, power, and digital communications vary by configured code
Performance
Series accuracy contextSLA5800 data-sheet documentation provides model-family accuracy specifications; exact accuracy should be tied to the configured calibration and option package rather than inferred from the base SLA5850 identifier alone
Repeatability and responseSLA5800 data-sheet documentation lists high repeatability and sub-second response context for SLA5850/SLA5860 class devices, subject to configuration and calibration conditions
Controls
Digital platformSLA5800 devices support analog and digital communication options depending on configuration, including RS-485/analog and fieldbus or Ethernet-based variants documented by Brooks
Applications
Application domainChemical and petrochemical research, laboratory, analytical, fuel-cell, life-science, production, and process gas handling applications
Observed variants
Stored auction gas/range combinationsAIR 500 SCCM (1), AIR 1000 SCCM (1), 500 SCCM (1); these are stored listing observations, not official model-wide specifications
