While you dont have it...

just scan (16 bits per channel) an stouffer T2115 transmission wedge alongside with your negative, at the same time with all image enhancing disabled, then in Ps just compare the gray values in a spot in the gegative with the patches in the scanned wedge.

perhaps not as convenient than a densitometer, but perfectly accurate. I've a densitometer but I use that way.
