These are the UTH's made in Scotland. I've tried it on a thermostat ( Herpstat, Ranco, and Johnson ) and the temps never get warm enough to the touch to do much good.
All hookups with multiple UTH's. If only one UTH were used the results might be better with the probe in place.

Right now my temps are great without the thermostat and it doesn't feel very hot to the touch when I move the aspen bedding aside. I've never measured actual temps, but it doesn't feel hot enough to burn my skin.

I'm using the Herpstat with my incubators only. The others are gathering dust.
