Herpstat 2---Probe placement/ Probe sensitivity?

[Eric Alan]

I have the same question but i have a glass tank and the temp controll probe is very large and if i place it between the glass and heat mat it moves most of the mat off of the glass and doesnt not heat efficiently...

For you, securing the probe to the under side of the heat mat will likely be best. In this case, having a good thermometer (temp gun highly recommended) will be critical. You'll be getting slightly different temperature readings on the bottom side of the heat mat, but this can easily be accounted for if you know what temperatures are the result of this placement inside your tank.

Edit: Obviously KMG is much less wordy than I am, and thus a couple minutes faster tonight. Ha-rumph...
