Compact UPRtek devices have small screens, but sometimes it’s more convenient to see all the data at once.  You may want to compare the CCT with the Spectrum and CIE chart all together, or any number of other combinations.

You can install the uSpectrum PC Software on a PC/laptop and then cable-connect to your UPRtek device.  It allows you a full PC workstation interface to your UPRtek device for operating, measuring, and then analyzing, juxtaposing and evaluating data.

It’s become one of our most popular features and it gives our users the data analytical tools to measure accurately, evaluate thoroughly and assess with confidence.
