Product overview

TR 520 is a portable d/8° sphere spectrophotometer with switchable dual apertures for fast positioning and repeatable colour measurement. TRA 520 adds a portable stand, optical cells and UV In/Out for liquids, powders and fluorescent materials.

Key features

  • 400–700 nm visible spectral range with 10 nm bandwidth supports spectral data and multiple colourimetric values.
  • An onboard camera aids positioning, while the 3.5-inch colour capacitive touchscreen displays results directly.
  • The rechargeable battery supports about eight hours or 5,000 measurements for laboratory, production-line and field use.
  • Included OnShade colour software supports data storage, analysis and quality assessment.
  • TRA 520 supports UV In/Out measurements for fluorescent materials.
