Brooks Instrument GF126 High-Flow PTI Mass Flow Controller
About this part
Brooks Instrument GF126C-200158 is associated with the GF126 high-flow thermal mass flow controller line. Brooks defines GF126 as a high-performance, high-flow model with pressure-transient insensitivity and integrated inlet-pressure measurement; the following C denotes MultiFlo capability. The published GF126 model envelope is 55–300 slpm N2-equivalent. The 200158 suffix is not defined by the published configuration-code sequence, so the configured gas, full-scale range, valve, fitting, connector, communications, calibration, and customer-special requirements are not established by this identifier alone
Configurations vary. Verify the exact unit before choosing a replacement.

Key Facts
Specifications
| Exact identifier | GF126C-200158 |
| Manufacturer | Brooks Instrument |
| Product series | GF100 Series |
| Device class | Metal-sealed high-purity/ultra-high-purity thermal mass flow controller for gases |
| GF126 model | High-performance, high-flow model with pressure-transient insensitivity |
| Configurability code C | MultiFlo capable |
| Current GF126 model envelope | 55–300 slpm N2-equivalent; the configured full-scale range of GF126C-200158 is not established |
| GF126 measurement context | Current Brooks model-code documentation assigns integrated inlet-pressure measurement to GF126 |
| Current GF126 accuracy context | ±1% of set point over 35–100% full scale and ±0.35% full scale over 2–35%, based on factory N2 calibration |
| Current GF126 repeatability context | Less than ±0.15% of set point |
| Current GF126 operating-temperature range | 10–50 °C |
| Communications context | RS-485/analog and DeviceNet configurations are documented; the installed interface requires the complete configuration code or physical-label evidence |
What Does GF126C-200158 Mean?
Only the GF126C prefix can be decoded from Brooks’ published product-code structure. The suffix must remain uninterpreted without an exact manufacturer record or readable physical label.
| Segment | Field | Interpretation |
|---|---|---|
| GF | Base model code | High-purity/ultra-high-purity digital mass flow controller platform. |
| 126 | Package and performance model | Current Brooks documentation defines GF126 as high-performance and high-flow with PTI; its model-code table assigns a 55–300 slpm N2-equivalent envelope and integrated pressure measurement. |
| C | Configurability | MultiFlo capable. |
| -200158 | Secondary suffix | Not defined as a valid continuation of the published GF100 Series configuration-code sequence. Do not assert a gas, range, fitting, connector, CSR, or other option meaning from this suffix. |
Configuration Software Status
MultiFlo capability does not identify the gas or full-scale range currently programmed into the controller.
