Testing milk for added water is an important quality control check carried out in dairies worldwide. Adding water to milk increases the freezing point of the milk by a fraction of a degree. This is measured using a machine called a Cryoscope which can detect added water in milk with precision down to a thousandth of a degree Celsius.

The Funke Gerber CryoStar is a highly accurate and reliable Cryoscope for high accuracy freezing point determination (FPD). The CryoStar uses FPD to find the plateau as prescribed in the ISO/IDF/DIN 5764 standard for measuring water in milk. The 4 decimal place accuracy of the CryoStar gives excellent repeatability and ultimately confidence in the instruments results.

Key Features

  • Designed for the future, flexible: Fixed time measurement, plateau and maximum search functions. You can freely program all relevant parameters. These will of course be recorded. And the CryoStar can also be set to conform with all national and international standards (including future ones).
  • Easy to use: The operation is menu guided on the touch screen in the language of your choice. German and English are currently available.
  • Sure Performance: The reliable cooling system ensures rapid operational readiness even in high-temperature environments (max. approx. 34°C).
  • Fast: Depending on actual setting used, up to 40 samples can be measured per hour.
  • Versatile: The CryoStar is equipped with a serial connection for standard printers und an USB port for connections to a PC. Measured values can be saved to a USB-drive for further processing.
  • Handy: The CryoStar is small, light and easy to handle. The percentage of added water content is directly displayed and printed. The calibration is carried out automatically. All settings and calibration values are retained in a non-volatile memory
