The good news is if the dataloger you get has a mems pressure sensor, you will have a high precision temperature sensor, whether or not the product software provides that resolution to you is another matter. In addition to the piezo-resistive bridge being mechanically sensitive to diaphragm strain, they are also great thermistors. Which ends up requiring a high resolution temperature sensor to temperature compensate the bridge readings.
Two related but off target products I would personally recommend is picking up a used EeePC as a usb data sink. I bought one of the originals back almost 10 years ago, and I still find it to come in handy once in awhile versus a rasperry pi, you could likely pick one up for nothing today. A USB labjack works quite well to tack up a few thermistors to a DUT for logging, it also has full driver support for linux/windows with a python interface (other languages too).
