The models of THE Kern ORA-W-Series are universal, maintenance-free analogueue handheld refractometers. The handy and robust design enables a simple, efficient and durable use in everyday life. Manual conversion effort is avoided by several selectable scales and excludes application errors. These scales are specially developed, precisely calculated and checked. They are also characterized by very thin and clear lines. The optical system and the prism cover are made of special materials, which enable a low-tolerance measurement. All models are equipped with an eyepiece with a simple and smooth adjustment possibility at different visual strengths. The models marked with "ATC" have an automatic temperature compensation, which enables exact measurements at different ambient temperatures.
