Digital mass flow controller model F4Q is a high-performance digital mass flow controller equipped with our original "micro thermal flow sensor".
Equipped with a large LED that shows the control status at a glance and a LCD that shows the status in detail.
Higher accuracy in a wide range of flow rates.
New functions to solve problems with flow rate control.

Understand the status of control at a glance

The color and state (e.g., flashing) of the LED indicator show the control status.
With the information-rich LCD, you understand the control status in detail.

Accuracy of 1 % S.P. in a wide range of flow rates

High-accuracy control for high and low flow rates.
Great for applications where the flow rate set point changes significantly.

High-speed response of 0.3 seconds over a wide range of flow rates

Response is fast whether starting control with a fully closed valve or changing the settings.
Even when the flow rates of multiple gases are changed at the same time, their ratio can be retained.
