Why does the humidity meter on the humidor show 100%?

1.When the humidity exceeds 80%rh, the pointer will go directly to 100%rh. This is done to allow you to see the excess humidity more clearly. This is because the optimal humidity for preserving cigars is around 70% rh. 2.If you want to reduce the humidity to 70%, you need to take the water box out of the humidor and debug it for a period of time to allow the temperature to cool down, so that the humidity will slowly return to normal values.
