Don't know about ISSPRO specifically, but normally a thermocouple (pyrometer) connects directly to a gauge without any separate power. The thermocouple generates a small voltage due to the effects of heat, and that voltage is enough to move the needle. Ones with digital readouts, amplifiers, cold-junction compensation, or other fancy lab-grade stuff need power, but normally a pyrometer measuring something that's way hotter than room temperate is just hooked directly to the gauge. Had an old industrial one like that that I put on my wood stove and it worked fine with no outside power.
