The large measuring range extends from 0°C to -60°C. A further  scale enables to determine the charging stateof lead batteries such  as z.B. car, motorcycle and boat batteries. By the large measuring range  of 1.100sg - 1.400sg and a outstanding resolution of 0.01sg even modern  heavy-duty batteries can be measured accurately. The scale has beside  the sg-value-scale a concrete indication of charge (charge / fair /  good). The automatic temperature compensation (ATC) makes possible the  employment of the equipment without restriction in different ambient  temperatures. The results of measurement are not falsified. Cheap products  without ATC must be newly calibrated for each deviation of the ambient  temperature or you receive incorrect results. Already 5°C temperature  difference play a crucial role!

Example measurement:
Before each measuring procedure you should clean the lift-up lid and  the prism carefully and afterwards dry to leave. Then you give 1-2 drops  of the sample on the prism, when closing the lift-up lid the sample  distributes itself evenly between covers and prism. Pay attention that  no air vesicles form. This would impair the fair result negatively.  By easy moving of the lift-up lid the sample liquid can be distributed  evenly. Now you hold the refractometer against bright daylight, in order  to see the scale by the eyepiece. The desired value can be read off  now directly. Please carefully clean and dry the equipment after each  measuring procedure, so that no deposits are left on the prism and the  cover.
