This 2-in-1 handheld refractometer is designed for measuring both sugar (Brix) and salinity concentration with precision. Ideal for brewing, winemaking, brine testing, and fruit analysis, it provides instant and accurate readings. Equipped with Automatic Temperature Compensation (ATC), it ensures reliable results regardless of ambient temperature changes. Compact, lightweight, and easy to use, it’s the perfect tool for professionals and hobbyists alike. Main Features Dual Scale Measurement – Measures Brix (0–32%) and Salinity (0–28%) on one device. High Accuracy – Measurement accuracy up to ±0.2% with clear, easy-to-read scale. ATC Technology – Built-in Automatic Temperature Compensation (10°C–30°C) for consistent results. Easy to Operate – Just place a drop of solution on the prism, hold to light, and read through the eyepiece. Durable & Portable – Lightweight design (140 g) with sturdy build, ideal for home or professional use. Wide Applications – Perfect for brewing, winemaking, brine testing, aquaculture, and fruit juice analysis.
