What’s the average Delta E difference between the SpectroDens and the Xrite eXact?

What’s the average Delta E difference between the SpectroDens and the Xrite eXact?

Both instruments are using nearly identical centroids which included the NIST white ceramic tile and therefore, both instruments are being calibrated to almost the same standard. As a result, from measurement data we’ve collected using field instruments in pressroom conditions, we have observed that a population of Techkon SpectroDens 4 units will agree with a population of X-Rite eXact units just about as well as the eXact units will agree to themselves.
