I received many complaints on noisy RoR signals over the year. The ongoing work of Scott Rao and a broken TC made me reconsider my own roast logging setup. As I had collected many different meters and probes over the years, mostly for development purpose, I wonder which one I should best install in my machine.

My goal was to minimize both, the signal to noise ratio as well as the introduced signal delay, especially for the RoR. Thus I came up with a setup that would allow me to compare different setups on the amount of idle noise they produce.

I switched from TCs to RTDs for reasons detailed in the post and I am quite happy with my new setup,
