Brooks Instrument 4850ABC2S1B1K5C00A Thermal Mass Flow Controller

Brooks Instrument 4850ABC2S1B1K5C00A Thermal Mass Flow Controller is a precision gas‑flow control device designed to monitor and regulate gas delivery in analytical, pilot, and industrial systems. This model is part of the Brooks 4850 family and is configured for 24 VDC power and an inlet pressure up to 70 psi, enabling straightforward integration with standard gas handling hardware. As a thermal mass flow controller, it uses a heated sensing element to determine gas mass flow and provides proportional control to a user‑setpoint, supporting accurate flow regulation across typical operating conditions. The full part number denotes a specific hardware setup intended for use in laboratory and industrial environments where exact gas flow is critical. Common applications include process gas delivery for analytical instruments, semiconductor fabrication, and environmental testing, where consistent gas flow directly impacts measurement or process outcomes. The device is designed to integrate with Brooks control interfaces and compatible ancillary gas‑system components, and is commonly paired with appropriate regulators and calibration standards to ensure correct gas delivery. By combining TMF technology with the 4850 series’ established configuration, this controller supports repeatable gas‑flow regulation in demanding processes.
