Very good point. I've often wondered about how accurate my DTP92 would be
after a few years of use. So, how do we get them re-certified/calibrated or
whatever?

Lastly, Roger and CDTobie both posed questions/responses about
recertification of instruments and whether an emissive colorimeter
should need this as compared to a spectrophotometer. I would contend
that ALL instruments should be recertified regularly. These are the
tools that you are basing your work on, and they should be maintained
like any critical part of your workflow. Yes, an emissive colorimeter
should require less frequent maintenance than a Spectral instrument, but
filters, diffusers and components age and any instrument should have a
regular maintenance schedule.
