Brian:
We think highly of JUST NormLicht products. You can’t go wrong there.
There is another less expensive way to gather ambient or light booth temperature readings…
Some measurement devices have an ambient sensing head (i.e.: X-Rite i1Display2/Pro, i1Pro/i1Pro2). Unfortunately X-Rite’s latest profiling solution ‘i1Profiler’ doesn’t currently provide an easy correlation to determine temp as did past software (i1Match, Profilemaker v5, etc.). But there are two solutions Pat Herold (Tech Support at CHROMiX) mentioned recently that can help correlate this information for you:
ColorConverter works on iPad. It is not free, but well worth the small investment. You can get more information at itunes
There’s also Bruce Lindbloom’s site. Not as convenient as an iPad app, but it’s a free option. Click the “Calc” button and choose the CIE Color Calculator.
Not sure this is what you’re looking for, but it might help provide other options.
