Curatorial RemarksThe PTR mark is probably from the Physikalisch-Technische Reichsanstalt, the German institute of metrology where it was likely calibrated and approved for official use.
FunctionThis is a thermometer for precise measurements around 0-5.5 degrees Celsius. This indicates it is likely to check the temperature of refrigerated liquids.
It seems to be approved for official purposes as it has a seal by the German metrological authorities.
