I found a digitally controlled pyometer on Ebay. Do these work like the stand alone ones that I just stick the k coupler into the hole in the kiln or do these need an electrician to wire it into the kiln? I just want to make sure I'm buying the right thing. The one I have now is not capable of putting a schedule into it, it just tells you the temperature of the kiln, so if I have to replace it I might as well look at upgrading so I don't have to babysit the kiln and manually ramp down.
I'm looking at this one on Ebay

or this one at Sundance that tells tempature digitally but not ramp down (the $44 one)
