In the past color analyzers in general were never real popular because inaccuracy can result due to the differences in spectral characteristics of the different dyes of color film, and differences in the spectral response of paper and analyzer probe. If you programmed with one type of film, and analyzed another, inaccuracy could result, so you needed to have different programs for each film type. But from what I understand, some of the later models such as the Colorline and Colorstar are very good in this regard as they found a way around these problems. I own a Beseler which occasionally suffered from these problems. So as my ability to color balance prints by eye improved, I just relegated its use to determining exposure for both color and b&w, and it works well for that. I am not familiar with the model you describe so can't really comment on how well it works but if you have it, good luck with it.
