Kern Analogue refractometer ORA 1WA

The KERN ORA-W series models are universal, maintenance-free analog hand refractometers. Their compact and robust design allows for easy, efficient, and long-lasting use in everyday life. The manual conversion effort is eliminated by several selectable scales, which prevents application errors. These scales are specially developed, precisely calculated, and verified. They feature very thin and clear lines. The optical system and prism cover are made from special materials that enable low-tolerance measurements. All models are equipped with an eyepiece that provides easy and smooth adjustment for different vision strengths. The automatic temperature compensation (ATC) allows for accurate measurements at varying ambient temperatures (10 °C–30 °C).
