The C6 HDR2000 Colorimeter is field-upgradeable with Calman, meaning that supported display technologies are automatically updated when the device connects with the software. Every C6 HDR2000 Colorimeter sold is first certified in Portrait Display’s calibration lab and shipped with a NIST (National Institute of Standards and Technology) certificate of accuracy.
The C6 HDR2000 is designed and specified to measure luminance accuracy at a range up to 2000 cd/m2.


  • Supports all display technologies including HDR, plasma, LCD LED, front-projection and OLED.
  • Field upgradeable for new display technologies and calibration tables with spectral characterization technology.
  • Advanced low-light handling with dynamic iris to optimize accuracy and measurement speed.
  • Luminance accuracy at a range up to 2000 cd/m2.
  • Advanced light and color dichroic glass filters provide spectral accuracy and environmental stability over time.
  • Sealed optics and sensors for increased lifespan.
  • NIST certified in SpectraCal’s calibration lab prior to shipping.
  • Built-in ambient light diffuser and tripod mount.

Meter Diffuser

The C6 HDR2000 includes an attached white disk diffuser for use when taking ambient light measurements or measuring direct light sources such as a projector in direct view mode. In all other modes, the diffuser is not used. The diffuser pops slightly away from the meter body and swings away from the lens.

Meter Positioning

Flat Panels and Rear Projectors

The C6 HDR2000 should be positioned with the face of the meter squarely in contact with the center of a flat panel or rear projector screen, to block ambient light. The cable counterweight can be draped over the top of the display to facilitate this.

Front Projectors

The C6 HDR2000 has a tripod mount for use in non-contact mode, to measure front projector screens. The C6 HDR2000 should be placed about three feet (1 meter) back from the screen.

Low Light Handler

When enabled, the low light handler averages multiple meter samples per measurement, when measuring light levels below the specified Low Light Trigger level.
