Handheld Refractometer LHRF-A10 - Optical Refractometer Labtron Handheld Optical Refractometer LHRF-A10 measures refractive index from 1.440 to 1.520 ND with 0.001 ND resolution. Automatic temperature compensation operates from 0 to 30°C using a 20°C reference temperature. A zero-adjusting screw and focus-adjustable eyepiece support field calibration. Suitable for refractive index testing of chloroform, benzene, toluene, turpentine, and other solvents in quality control, chemical processing, and laboratory inspections. #LabEquipment #LabRefractometer #Labtron https://www.labtron.com/handheld-refractometer/lhrf-a10
