Kern's ORA-U series is specifically designed for use in industrial and automotive applications and measures (functionality depends on model purchased) Adblue/glycol concentration (ethylene, propylene), battery fluid, urea, the freezing point of fountain solution and refractive index.
This refractometer can be used in a wide variety of applications including car workshops and car production, chemical industries, antifreeze monitoring in the solar industry, geothermal applications such as measuring brine-concentration of ground heat and by forestry and lumbermen.
Some models come as standard with automatic temperature compensation (ATC) which will maintain accuracy in different ambient conditions.
Includes 2 year warranty as standard.
