The KERN ORA-E series models are universal, maintenance-free analog hand refractometers. Their compact and robust design allows for easy, efficient, and long-lasting use in everyday situations. Manual conversion efforts are eliminated by several selectable scales, which prevents application errors. These scales are specially developed, precisely calculated, and verified. They also 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 package includes a storage box, calibration solution, possibly a calibration block, a pipette, a screwdriver, and a cleaning cloth. Additional accessories are available optionally. This model has a particularly large measurement range for Brix value measurements due to a split scale. Its main areas of application are universal, especially in situations requiring an extra-large measurement range.
