Brooks Instrument TR Series Thermal Mass Flow Controller
About this part
5850TR/GA1C1B2AACF is a configured Brooks Instrument 5850TR TR Series thermal mass flow controller identifier observed in auction evidence. Official Brooks 5850TR documentation supports the model-family identity, MFC function, 15 VDC and 24 VDC manual context, configurable model-code structure, and family-level performance specifications. Treat the AR gas and 25 SCCM range as observed configured-unit evidence from listing data, not as a universal 5850TR model specification, and verify gas, range, seals, fitting, cable, power, approval, calibration, and service compatibility from the physical unit label and calibration records
Unit-specific configuration
Observed configuration
Historical listing records identify this part as AR at 25 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.
Application classSemiconductor/high-purity gas delivery

Specifications
Identification
Configured part identifier
5850TR/GA1C1B2AACF
Model family
Brooks Model 5850TR / TR Series MFC
Device type
Elastomer-sealed thermal mass flow controller / mass flowmeter-controller platform
Official legacy status
Brooks legacy products documentation identifies Model 5850TR as an elastomer-sealed thermal mass flow controller and provides separate 15 VDC and 24 VDC installation manuals
Function
Control architecture
Brooks 5850TR documentation describes the controller as a gas mass-flow measuring and controlling device with a flow sensor, control valve, and integrated electronic control system
Configuration
Configured-unit rule
Gas, full-scale flow, valve type, operating pressure, I/O type, connector, fitting, cable, power supply, approval, seal material, OEM code, and calibration details vary by full model code and unit label
Model-code context
The Brooks 5850TR model-code table documents the /G mass flow meter/controller base and option positions for seals, valve type, electrical I/O, mechanical connection, cable, power input, approvals, and OEM code; no verified official document is currently available in this pass names the full GA1C1B2AACF suffix
Performance
Accuracy
Brooks 5850TR manuals list +/-1% full scale accuracy including linearity measured at calibrated conditions
Repeatability
Brooks 5850TR manuals list +/-0.25% full scale repeatability
Rangeability
Brooks 5850TR manuals list 50:1 rangeability
Flow
N2-equivalent family flow range
Brooks 5850TR manuals list any full-scale range from 10 mln/min to 20 ln/min based on nitrogen equivalent; the exact configured gas and range must be read from the unit label or calibration records
Electrical
Flow output and setpoint context
Brooks 5850TR documentation includes 0-5 VDC flow output/setpoint input; the 24 VDC manual also documents current I/O options depending on model code
Power supply versions
Brooks manuals cover +/-15 VDC and +24 VDC configurations; the 24 VDC model-code table also documents a +15 VDC-only power option
Pressure
Operating pressure context
Brooks 5850TR documentation lists 100 bar versions, while the 15 VDC manual also references 100/300 bar versions; pressure capability is configuration-dependent
Environmental
Ambient/gas temperature
Brooks 5850TR manuals list ambient/gas temperature range of 0 C to 65 C
Leak integrity
External leak integrity
Brooks 5850TR manuals list outboard helium leak integrity of 1 x 10^-6 mbar l/s
Materials
Wetted materials context
Brooks 5850TR manuals list stainless steel wetted parts with Viton, PTFE, Buna-N, or Kalrez depending on configuration
Mechanical
Mechanical connection options
Brooks 5850TR documentation lists options including 1/4 VCR, 1/4 VCO, 1/4 NPT, 1/8 or 1/4 tube compression, 9/16-18 UNF, 6 mm tube compression, and 1/4 Rc/BSPT depending on configuration
Observed configuration
Stored auction gas/range context
Stored auction evidence for this exact configured identifier describes AR gas and 25 SCCM full-scale flow; this is observed configured-unit context only
Applications
Application domain
Semiconductor gas handling, analytical equipment, environmental instrumentation, process gas, and other manual, electronic, or computer-controlled gas-flow applications
