The Herpstat 2 has 2 separate temp probes and outlets. On the display you will see 2 lines of display too, one for the left outlet and probe and one for the right outlet and probe. Its basically just 2 Herpstat ones in 1 box. As for shedding, Muriel will probably shed pretty soon. My snakes as babies shed about once a month. They go through growth spurts where they will shed pretty fast, then slow down and shed maybe every 2-3 months. I wouldn't worry about although on albinos and sunglows or any white snake, it can be hard to tell. I can only tell when Dottie is going into shed when she is in the deepest blue and that's because of her eyes. Vicky I cant even tell when she is going into shed except her red gets dull and doesn't pop.
