I was just looking at the same one.
The 50 series can return a value within +/- 0.3 deg C, regardless of the thermocouple used. The T type probe though, would have an absolute error of +/- 0.5 deg C, where a type K would be +/- 1.5 deg C.
[edit: rambling removed]
The different models have various extra features, like logging, dual input (and differential output), etc...
