Advanced high-speed response, low pressure loss, and high-accuracy digital mass flow controllers 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. Flow rate 100 % F.S. Large LED and liquid crystal displays show control status at a glance Higher accuracy in a wide range of flow rates New functions to solve problems with flow rate control Low-differential pressure structure allows...

Notes on Model Selection Before installation and use, please read the notes and precautions in the user’s manual ● Do not use the product for gas that is within its explosive limits. Doing so may result in an explosion. ● If an abnormality in the controller is likely to result in damage, an appropriate redundant design should be used. ● If there is a possibility of foreign matter entering the device, install an upstream filter, strainer, or mist trap capable of eliminating foreign matter 0.1 μm or greater in diameter, and be sure to periodically inspect and replace the filter. ● When the...
