Design and optics: The refractometer features a compact, streamlined design with an internal assembly of optical glass lenses. The large cover provides a secure fit with the lens, and the copperplated body delivers durable, quality construction. Materials and durability: Copper construction emphasizes precision manufacturing, enhancing durability and giving the instrument an elegant appearance. Automatic temperature compensation: Equipped with automatic temperature compensation, it adjusts for temperature variations to deliver precise readings consistently. Clear and precise readings: Using imported lenses, it displays clear and welldefined scales. The calibrated markings are easy to read, enabling accurate and efficient measurements. Applications: Suitable for onsite quality checks in beverage and food processing to monitor liquid concentration and consistency; useful in laboratories for routine liquid refractive index measurements in research and QC workflows; handy for field inspections during production, transport, or storage of liquids.
