I will talk to Fernando about whether he can measure if it puts out any significant noise.

Fernando says he has no way currently to measure radiated noise, but he is not concerned with this system because thermocouple voltage measurement circuits usually do not generate much noise. If in practice they do generate noise he knows of low-noise readout systems we could use instead.
