Quick, dependable measurements with builtin temperature compensation make this refractometer an essential tool for anyone who needs fast, accurate liquid testing. Designed for ease of use, it removes guesswork from refractive index and concentration readings by automatically adjusting for temperature changes so results remain consistent across a range of working conditions. Key benefits Accurate readings with Automatic Temperature Compensation (ATC) — compensates for normal temperature variation so you can trust results without manual correction. Fast, simple operation — place a drop of sample, close the cover, and read the scale immediately through the eyepiece. Portable and durable — lightweight, handheld design lets you test in the lab, on the production floor, in the winery, or in the field. Reduces waste and rework — reliable measurements help maintain product quality and consistency, saving time and materials. What it does and why you need it Delivers reliable refractive index or concentration readings for liquids where precise control of concentration matters (food and beverage, brewing, winemaking, honey, sugar solutions, chemical processing, aquaculture, and more). Removes the need to manually correct readings for temperature, reducing operator error and speeding up routine checks. Helps monitor and control product quality, verify incoming materials, and confirm finished goods meet specifications.

Userfriendly features Onedrop sample testing — conserves materials and speeds up workflows. Simple calibration using a standard reference (e.g., distilled water) to maintain accuracy over time. Clear optical scale for easy reading and minimal training for operators. Protective case and cleaning cloth included for safe transport and maintenance. Typical applications / use cases Winemaking and brewing: Monitor sugar concentration during fermentation to determine progress and ideal harvest or bottling time. Food and beverage quality control: Check Brix or concentration in juices, syrups, jams, and honey to ensure consistent sweetness and product specifications. Aquaculture and hobbyist saltwater tanks: Verify salinity and solution concentration for healthy aquatic environments and consistent system performance. What's included Handheld refractometer with Automatic Temperature Compensation (ATC) Protective storage case Calibration/cleaning cloth and basic user instructions Practical tips Calibrate regularly with a standard reference to maintain measurement accuracy. Clean the prism surface after each use to avoid crosscontamination. Allow the instrument and sample to equilibrate briefly if moving between very different temperatures for performance. This refractometer with Automatic Temperature Compensation is a straightforward, reliable tool for anyone who needs quick, repeatable liquid concentration measurements without the complexity of manual temperature adjustments.
