In some laboratories we can still find many instruments in use, which do not offer automatic reading of their results. In such cases the laboratory personnel is responsible for reading results which could lead to errors. One such instrument is the Advanced Cryoscope 4D3, which measures freezing point of milk, usually referred to as freezing point depression or FPD. At the company Labtim d.o.o. we are providing support and maintenance for this instrument. Cryoscope results are shown on its integrated display and sent through its RS-232 port. We developed a system, which automates the reading of cryoscope results over RS-232 connection and transfers them via web connection. The system also incorporates sensor for measuring ambient temperature and relative humidity.
