Thank you,

So If I have a heat mat and a CHE I need to have 2 tstats and 2 thermometers (one to measure the hot and cool side and another one to measure under the substrate)?

Heat mat- Tstat.
CHE- Tstat.

One probe under the UTH, one probe under the substrate, one probe above the substrate in the hot side and one probe in the cold side?

Did I get it right?

Is there an easy way to do it?

Thank you
