Hmmm. I gave a quick check of GELighting.com; no mention of anything to measure color temp, just an explanation.
I can't remember ever seeing any type of meter to do that. All I have ever used (and thought of) was a basic light meter.
I have a BEHA, small handheld analog, that's OK. For serious work a BEHA digital 93-1065F. Both are 'old' and have served me well. I still have both.
