Bench-top Color Spectrophotometer for Powder and Masterbatches

Large Aperture Bench-top Spectrophotometer Introduction

Large aperture bench-top spectrophotometer adopts D/8 geometry, with 50mm large test aperture, specialized in color measurement and color comparison of non-transparent materials such as powder, masterbatches and so on. The spectrocolorimeter not only has various  color spaces and color difference formulas, but also can display spectral reflectance curves, which is widely used in color management and quality control in the fields of paint, plastic, food, medicine and so on. The colorimeter  also provides professional mobile APP and PC software to support data export and report printing.
