This honey refractometer provides fast, battery-free concentration testing for honey and other liquids. It is designed for home, student, or professional use and emphasizes hygiene, safety, and durability. Key benefits - Quick, accurate measurements without batteries or digital readouts, easier and more affordable than digital meters. - Portable and simple to use anywhere, ideal for on-site quality checks. - Durable, hygienic construction that resists abrasion and corrosion. What makes it stand out - Material and build: nonstaining, noncorrosive, and nonreactive chromium material ensures hygiene and safety for all users. Main body is aluminum alloy; internal optics use a high refractive index lens for a precise optical system. - Performance: high quality optics with smooth focusing deliver reliable readings. The refractometer operates on the principle that liquid refractive indices change with concentration. - Versatility: designed for honey but suitable for measuring other liquids. Can be used to measure general corrosive liquids due to its abrasion and corrosion resistance. Specifications and contents - Principle: refractive index varies with concentration, enabling quick assessment of liquid strength. - Size and weight: 8 inches x 3 inches x 2 inches; weight 8.6 ounces. - Accessories: dropper, screwdriver, user manual, cleaning cloth, all included in a hard compact case. Use scenarios - Beekeeping and honey production: rapid quality checks of honey concentration in field or during processing. - Home kitchen or culinary testing: verify honey sweetness or consistency for recipes and product labeling. - Small labs or professional settings: convenient concentration measurements for various liquids, including general corrosive liquids, with durable, portable optics. This refractometer combines a robust aluminum alloy body, a precision optical system, and user-friendly design to provide reliable, hygienic, battery-free measurements wherever you need them.
