Hello all. We have an Anton Paar HTK1200N installed to PANalytical X'Pert PRO MPD with PIXcel detector. Changing between sample stages is easy and fast as stated before. I'm been measuring mostly thin films in O2, N2, air and vacuum, but I've also done some powder experiments. So far I've trusted manufacturers guarantee for temperature readings. Measuring with PIXcel is generally very fast (at least for powders) but as I've done most of my measurements in grazing incidence, I've used PIXcel as point detector which obviously increases the measuring time.
I don't have any experience with ovens from other manufacturers, but this combination seems to work very well.
