Measuring range: Brix 0-90% Minimum scale: 0.2% Measurement accuracy: Brix 0.1% (10-30) Features: 1. High precision prism: High uniformity, no cracks, good transparency, high dispersion and small temperature coefficient. The surface of the prism material is not affected by humidity. 2. ATC automatic temperature compensation technology: High quality temperature compensation film, certified size can reach the corresponding temperature compensation function. 3. Pure copper body: Solid texture, precise machining, solid structure, long service life, effectively improves the durability and accuracy of the instrument. 4. Measuring range: 0-90% Brix (sugar content), resolution: 0.5% Brix (sugar content). Automatic temperature compensation (10-30C) and calibration screw (calibration "0"). Easy to operate. Place 2-3 drops of the sample on the main prism, close the cover plate and look through the viewing window to read the Brix value. 5. Wide range of applications: No battery required, easy to operate and carry. Suitable for industrial, household, fruit, vegetable, jam, lubricant, emulsion applications.
