how can we measure two different temperatures in one temperature controller?

We have two thermocouples mounted in a tank and we need to measure both temperature of respective thermocouples in one temperature controller.

Answer 1

You need a dual-channel temperature controller. That, or some way to swap out the thermocouple leads.
