Macbeth TR-927 Transmission & Reflection Densitometer. The transmission seems to work. We did not calibrate it we just tried it out. We don't have the proper film to calibrate it.
See photos of the readings we got from neutral density gels and a color gel we had laying around. Seems to work pretty good for transmission readings. The reflection meter needs a light bulb and hopefully that is all to make it work. The light bulbs are probably not made anymore.
