Temp & humidity problem

[alley cat]

I have had some more eggs laid today by my Horsfields so whilst I was putting them into the incubator I added the new temp/hygro unit that had arrived, I already have one in the incubator and a temp only one. The problem is that the new one is reading 33.3c/86% whereas my other one says 32c/73% (which is actually the highest humidity reading it has given since my other eggs were put in there, it has not been above 70% before) also my temp only is reading 31.2c
So which one do I go with? worried now
