Kern Analogue refractometer ORA 4AA

The KERN ORA-AL 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 multiple 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. The automatic temperature compensation (ATC) allows for accurate measurements at different ambient temperatures (10 °C–30 °C). All models come equipped with an eyepiece that provides easy and smooth adjustment for different vision strengths. Included in the package are a storage box, calibration solution, calibration block (if applicable), pipette, screwdriver, and cleaning cloth. Additional accessories are available optionally. This model is particularly suitable for determining the sugar content of the wort in beer while it is still unfermented. The Plato scale allows the value to be read directly without conversion. The main areas of application are for brewers.
