Product Introduction
The nitrogen controller is equipped with an oxygen concentration analyzer. Control the size of the intake nitrogen valve based on the measured oxygen concentration in the environment. When the oxygen concentration in the environment is high, the proportion of valves is large; The oxygen concentration is low (meeting the set requirements), and the proportion of nitrogen valves is small or closed. Automatically control the oxygen concentration inside the atmosphere protection furnace, without the need for manual intervention, thus saving nitrogen and effectively reducing the cost of equipment operation.
