Output of the measured values is optional via a printer or a data transmission software on the PC via the RS 232-interface. The measurement and the documentation of the temperature in the sample can also be carried out by means of an optional digital temperature probe. In addition to the proven PVDF-coated glass capillaries, steel capillaries (such as for highly alkaline samples) are available.
