| Digital Abbe refractometers. To measure liquid and solid samples such as plate glasses, plastic sheets, and other solid films. By very simple operation that needs only to set the boundary line of refraction at the cross hairs, this refractometer directly indicates a measured value in digits together with temperature on the display. This refractometer enables anybody to carry out measurement easily without reading of analog graduation. Automatic temperature compensation. Dispersive value cannot be measured by this refractometer. |
