Features
The KERN ORA refractometers are universal, maintenance-free analogue handheld
refractometers. The handy and robust design allows the easy, efficient and sustainable use in everyday life. Manually calculated conversions and errors of the user are avoided by multiple selectable scales.
These scales are especially developed, exactly calculated and checked. They are also
characterized by their thin and clear lines. The optical system and the prism cover are made of special material which allows a low-tolerance measuring.
All ORA models are equipped with an eyepiece for easy and smooth setting for many different diopter strengths. The models marked with “ATC” have an automatic temperature compensation which enables accurate measurement at different ambient temperatures (10 °C/30 °C)
The following accessory-parts are included:
- Storage box
- Calibration liquid
- Calibration block (if required)
- Pipette
- Screwdriver
- Cleaning tissue
Further accessories are optionally available

Scope of application: Sugar
The following models are particularly suitable for the measurement of the “BRIX” value. They are used to determine the sugar content in food, especially in fruit, vegetables, juice and soft drinks. In the same ideal way these refractometers serve for monitoring processes in the industry (coolant monitoring, oils, water-based mixtures).
The main scope of applications is:
Industry: Monitoring of lubricants for process and quality control
Food industry: Beverages, fruits and sweets
Agriculture: Determination of the degree of ripeness of fruits for quality control in harvesting
Restaurants and large-scale catering establishment
