Please Help! My ZooMed Terrarium is too cold:(

[Eric Alan]

Is there one that has a prob so I can position on top of the heat pad and automatically regulate the heat?

A Hydrofarm (or JumpStart) or Herpstat thermostat will do what you need it to here. You'd put the probe for either of these sandwiched between the heat pad and the glass (on the outside of the enclosure) and dial in your temps from there. Once that's done, the thermostat will keep itself there and adjust itself as needed with the room temp fluctuations.

EDIT: The Herpstat is what I recommend. The Hydrofarm is a budget option.
