MK550T Spectroradiometer

The MK550T Spectroradiometer

Introducing the UPRTEK MK550T Spectroradiometer! Want accurate light measurements? Measure with precision today! Get yours now.

Companies that manufacture, buy, and sell display panels face a similar problem.  That is the need for efficiently measuring Display Panel performance in various situations, like on production lines, R&D test labs, and FAE offsite locations.

The choices are few. Use a Colorimeter that is portable but inaccurate or you can use laboratory-level equipment, which is accurate but slow, bulky, and expensive.

With the MK550T handheld spectroradiometer, anyone has access to cost-effective, lab-level instrumentation that can measure more than 10 times faster than other precision instrumentation.

The MK550T is used in manufacturing R&D development. It is used on production lines interfacing with manufacturing production equipment.  It is used by Field Application Engineers for remote site OEM/ODM work.

MK550T – Boost versatility & flexibility in measurement capabilities through portable, fast performance.

  • Laboratory-level precision – -diffraction grating and proprietary technologies
  • Different receptor sizes (for small-size displays – e.g. watches)
  • SDK allows manufacturers to integrate with their own RD efforts
  • Supports several 3rd party tuning tools
  • JEITA, Contrast, VESA, RMS, FFT Flicker metrics
  • Handheld versatility and can also mount on a stand, cable connect to PC for hands-free operations.
