When I calibrate it using the salt and water method, it shows 75% correctly. But when I put it back in the humidor it's showing 50%, when my electronic xikar is showing the correct 70% (Using xikar gel as humidification source)
Not sure why it reads correct in the sealed bag with the salt water, but wrong in the humidor itself. Looking for a replacement.
