That temperature difference exists because your freezer is not working as intended.

What is the size of the freezer? What refrigerant do you use?

Re: temperature higher than set temp(-80c) at the bottom of freezer
Need more information, what brand of 'ultra low temp freezer' is it? What are you using it for and how often is the door open? Is there heavy ice build up inside the freezer? If so, relocate whatever is inside, defrost the freezer and restart. With heavy ice build up, oil logging is common with ULT freezers, this will cause poor performance
