Ebay is useful sometimes I've not found any T'-key company site but with those Ebay ones being 122F with product code 050-15 and 50C = 122F , then The one I have the middle code is 125-?15 so probably 125 degrees C = 257F. The top code is probably date and the bottom one a batch number This one I took to 120 degree C without it changing state. For the archives, no replies now necessary.

The T220 is probably the model. The temperature would be one of the inkjetted values. I'd thimk maybe 125 centigrade. What is this from?

My conclusions on this one on
