Hello dcset,

UNI is  an italian   norm

Reference tolerance: UNI 7937, IEC 751 norms:
± 15° C at 0° C for A class (1/2 DIN)
± 30° C at 0° C for B class (1 DIN)
± 10° C at 0° C for 1/3 DIN class

Must be wrong, a PT100 where ice measures anywhere between -30 & +30 degrees?  

RE: what does means this on a pt100

Yeah, that is ridiculously bad performance. Who could possibly use that?  I think he meant ± 1.5° C etc., etc.

Quick Googling and here are the results:

Reference tolerance: UNI 7937, IEC 751 norms:
± 0.15° C at 0° C for A class (1/2 DIN)
± 0.30° C at 0° C for B class (1 DIN)
± 0.10° C at 0° C for 1/3 DIN class


See how important the dots are!
