CryoStar l and CryoStar automatic freezing point determination apparatus

With the CryoStar l and the CryoStar automatic, you can quickly and reliably determine the extraneous water content in milk.
You can choose between fixed time measurement, plateau search or maximum search. All key parameters are programmable and are of course logged, so that the units can be set up for all national and international standards (even future requirements).
The operation is menu-driven in the language of your choice. Currently, more than 10 languages are available. Additional languages are continually added.
A new cooling system quickly brings the unit to operating temperature even at high ambient temperatures.
Depending on the settings, you can measure up to 40 samples per hour.
Both units have a parallel port (for common printers) and can be connected to a PC with the serial interface. The necessary software is included.
The CryoStar l and the CryoStar automatic are small, light and easy to use. They give you a direct readout of extraneous water content, and a printout. Calibration is performed automatically. All settings and calibration values are permanently stored in a non-volatile memory.
