I use a HerpStat to regulate my under tank heater, and I trusted that the reading it showed was correct, but every time I would touch the floor of the tank with my hand it would feel warm to my touch, which I thought was odd because 90 degrees is about the same as skin temperature so it shouldn't feel warm.

I shrugged it off as me just having cold hands, but recently I acquired an infrared thermometer from Exclusive Snakes at a reptile expo so I could double check my temperatures, and it read perfectly on the cool side, matching the thermometers I have there, but on the hot side it was reading a good 6 degrees higher than what the HerpStat was telling me!

So I tried to adjust the thermostat accordingly but it only lets me adjust to within 2 degrees. So now it reads 85 and it's really about 90 - 91 when I use the infrared thermometer, and it's no longer really warm to the touch.

I'm just wondering if anyone else had to recalibrate their HerpStats and if anybody had one as off as mine was.
