what is the difference between the yellow and the blue ?

If the “blue” reference is the thermocouple with white and blue sheathing, it’s only the material covering the K thermocouple. Both sets are “K” thermocouple.

I need to order separate k-probes in the 500c range, doe this use the standard "mini-connector" for the probes?

Yes, it is mini K-Type connector with flat-pin.

Is the included 1.9V battery rechargable?

Hi, it comes with 9V battery and it's not rechargeable

How long are the wires for probes or other type?

Hi, the cable length of the Bead-type K-type Thermocouples is about 95cm/37.4" and for the Stainless Steel Type K-type Thermocouples is 90cm/35.4".
