Can the tc0521 use an external power source instead of batteries? what happens if i need to record using bluetooth past the expected 30 hr of battery?

Yes, you can use the USB slot to power it up for long time. You can use Bluetooth to transfer data to mobile phone and PC with our software

What size/kind of 9vdc plug it requires? standard 5.5mm x 2.1mm is a way too big?

Voltage 9 VDC ( 8-10VDC Max ). Plug diameter : 3.5mm

How long are the probes?

I don’t remember if it came with one, but most of the ones I have are about 3’ long. I use K-type thermocouple leads, K-type probe and a few other K-Type testing accessories with this device and it’s been pretty good so far.
