Abbe Refractometer Monocular Multi‑Specimen Compatibility, Versatile Property Analysis, for teaching and geological‑Survey Tasks

【Professional Measurement】Adopting critical‑angle optical principle, this unit can test ND refractive index and NF‑NC dispersion value for transparent and translucent liquid and solid samples. It outputs consistent, repeatable measuring data, effectively reduces measurement deviation caused by sample differences, meeting strict requirements of professional laboratory detection tasks. 【Precise Manual Adjustment】Equipped with dual handwheels for refractive‑index scale and dispersion fine‑tuning. Samples receive light through the incoming prism, users can observe distinct boundary lines inside the field of view. You can tweak knobs until color fringes disappear to finish calibration, bringing simple and accurate manual operation during testing. 【Broad Testing Spectrum】Covers ND 1.3‑1.7 refractive index range and 0‑95% sugar concentration detection. It supports multi‑dimensional analysis including purity, concentration and dispersion property. Whether you handle liquid solutions or solid test pieces, it can respond to various types of sample testing demands. 【Optimized Hardware Configuration】Fitted with high‑transmittance high‑resolution prism for sharp data observation. It combines optical dial reading together with digital temperature readout, supports temperature unit switching. Matched with thermostat connector, it stabilizes testing environment and helps users obtain more reliable and precise measuring outcomes. 【Versatile Industry Compatibility】Well‑suited for petroleum, pharmaceutical, food processing, sugar manufacturing, coating and daily‑chemical sectors. Also applicable for geological survey, university teaching and scientific research laboratories. It can complete routine sample analysis for production quality‑control and classroom experimental projects.
