The UPRtek Spectros are portable spectroradiometers, suitable for colourimeter matching as well as direct measurement use.

  • ColourSpace INF/XPT/PRO & HTX/HTP
  • 9nm Spectral Bandwidth
  • Handheld & Tripod Models
  • 0.001 to 5000 cd/m2
  • 10mm Receptor Size

ColourSpace Integration

As with all probes, operation and function is controlled via the Probe Options menu, accessed via the Profiling window, with the left-hand side of the menu providing generic probes settings, and the right-hand side settings specific to the UPRtek spectros.


UPRtek MD100N/MK550T Settings

The Settings options provide specific UPRtek configurations. Full details for all options can be found within UPRtek's own documentation.

Exposure Mode

Exposure mode is Auto or Manual, with the default being Auto. When set to Manual, the Exposure (uSec) options becomes active.

Exposure (uSec)

Exposure (uSec) can be set manually when Exposure Mode is set to Manual.

Exposure Time

Exposure Time is Fast or Normal, with the default being Fast.

Measuring Times

Measuring Times is the number of raw measurements averaged to give the resultant measurement value.

Sync Mode

Sync mode is On or Off, with the default set to Off. When set to On, the Sync Freq. (Hz) box becomes active.

Sync Freq. (Hz)

The Sync Freq. (Hz) option enabled the frame rate of the input video signal, or display refresh rate, to be set manually.

Average Low Light

Average Low Light is a probe generic option, that averages multiple readings in low-light situations using an advanced algorithm built into ColourSpace. The algorithm varies based on the probe in use to provide the best possible results.

Probe Adjustments

Probe Adjustments are generic probes settings, with consistent operation regardless of the probe in use.

Configure Matching

Probe Matching is really unnecessary with the UPRtek, as it is a Spectroradiometer.
The options is provided on a Why Not basis...


Probe Offset enables a user to manually enter offset values for different probes/display combinations.
Perceptual Colour Match is a preferable approach.

Extra Delay

Extra Delay sets a delay time after the patch has changed before probe measurement starts, and can be set automatically via the Auto button, and manages signal path delays in the image pipeline.
When using the Auto option, Average Low Light should not be enabled.
