Hey, electronics gurus, I am working with thermocouples in my cast iron foundry and would like to come up with a reference millivolt source so that I could calibrate and confirm calibration ongoing of a device that would read the thermocouple output to four significant figures. The voltages in question would range between 0.000 and 20.00 mV with the area of greatest interest being around 15.00 mV.
I have been trying to locate a reference voltage source in the 10 to 200 mV range that I could use to check my voltage measuring system to ensure that the gain in my system is correctly adjusted. So far, I have found precision voltage generators in the 200 to 500 dollar range. But, I suspect there is something out there much cheaper.
Any help?
