"The Large Area View Color Measurement System","The D25LT Colorimeter has a large viewing area that is optimized for measuring the color of coarse, non-homogeneous and irregularly shaped products. It can be used in the food industry to measure samples such as cookies, crackers, chips, beans, spices, pasta and soups or in other industries to measure products such as ceiling tile, carpet, chemicals and minerals. The D25LT is a self-contained instrument which saves precious bench space. The one-piece instrument includes a large, color LCD touch screen for clear viewing of color measurement data as well as entry of parameter selections. An alphanumeric keypad displayed on the touch screen simplifies sample identification and data entry. The system is network and PC compatible and its built-in printer provides a hard copy of results.","The D25LT Colorimeter can be ordered with the sample measurement port of the optical sensor facing up, to measure samples such as pasta, beans and soup through the clear bottom of the sample cup. Or it can be ordered with the port facing down to measure samples such as chips through the open top of a cup."
