can this unit feed the data straight into a computer instead of using a SD card, I dont want to have to pull the card out every now and then for data

No, there is no realtime or batch data access. But I have had no trouble using the SD card and importing the files into spreadsheets (for example).

can these temperature probes be left in a home cooking oven up to 450 degrees for a few hours at a time?

The probes come with the set cannot be left in a home cooking oven up to 450 degrees,but if you replace them with other probes with measuring range over 450 degree,then it is ok.

Does this unit record humidity readings also?

no just records temperatures very good value and accurate for measuring temperatures

is their an ac power for this unit? and where would get it.

Hi, the power adaptor is not included in the set. If you want to buy it, you may contact our customer service(gainexpress) to get the price and production lead time of the power adaptor through amazon message.
