Portable Spectrophotometer LSP-A31

Name: Portable Spectrophotometer LSP-A31
Brand: Labtron
SKU: LSP-A31
Rating: 4.7 (951 reviews)

Portable Spectrophotometer LSP-A31 is adopted with 45/0 geometry (45 ring shaped illumination, 0 degree observation angle), where the standard white board is included in the optical system for great accuracy of every measurement. Equipped with automatic gloss compensation technology ensures the accuracy of the color measurement data for the surface of different gloss. Large data storage space up to 20000 samples measurement records. The measurement of the color of the powder, granules and other materials can be done by adding the powder accessories to this spectrophotometer.
