UTH with dimmer switch?

Unregulated a Zoo Med matt can go to 120*F. Yes it needs a thermostat or at least a dimmer switch.

Last year I took in ball python burned by an unregulated heat source. The vet bill was $400 and she still died due to sepsis after two weeks.

I did in fact buy a dimmer, but I am now thinking of using it for a CHE to keep the temps on the cool side up a tad.

90 degrees where?
You should be taking temperatures UNDER the substrate, the hottest area your animal can touch.

Uth always need to be regulated by a thermostat or dimmer....no exceptions.
