Controlling airflow is very important during roast. Normally,for WS-300, we control airflow is only by electric damper.
But once you forget to clean up the exhaust pipe and exhaust fan motor in time, the dust and chaff may block the pipe or motor, or if you meet the bad weather (like strong wind, heavyrain etc.), you may not get exact pressure value by manual damper.
Then the hot air pressure gauge can help you get the real airflow pressure value in any condition, that makes your roast more precisely.
