The KERN ORA-F 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. The manual conversion effort is eliminated by several selectable scales, which prevents application errors. These scales are specifically developed, precisely calculated, and verified. They are also characterized by 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 simple and smooth adjustment for different vision strengths. The automatic temperature compensation (ATC) allows for accurate measurements at varying ambient temperatures (10 °C–30 °C).

Included in the delivery are:

• Storage case
• Calibration solution
• Calibration block (if applicable)
• Pipette
• Screwdriver
• Cleaning cloth

Additional accessories are available optionally. This model is particularly suitable for measuring and determining glycol concentrations, battery fluid (BF), and freezing point measurement of windshield washer fluid (CW). Furthermore, these models are suitable for measuring temperature exchange systems.

Main application areas:

• Automotive industry
• Chemical industry
• Solar industry (frost protection control).
