This device can be installed on F1/X2/A1/A20 dry cabinet. When the door is open and relative humidity raises up, the QDN will fill the nitrogen air automatically to speed up the recovery. It will stop the inflow of nitrogen air when preferred humidity inside the cabinet is reached. So the nitrogen won’t be pumped in continuously.
