Hi I'm using thermocuple as a temp. sensor, it is inside soldering handle output is 0 mV (tested with digital voltmeter at range 200 mV) at room temperature.
I'll amplify that voltage using AD623
I cannot use Ice bath to set ref. junction at 0 deg C. I thought using table (ref junction at 0 deg C) and formula to calculate temperature.
My question is what max error without using any compensation will I have.
Will it be actual temp of soldering hand + room temp or will it be low error like +-1 deg C which will suit me (I don't need it to be so precise)?
I will regulate temp automaticly from 160 deg C to 460 deg C
