This gage has two scales, one for optical density running in a logarithmic manner from 1.5 to 0 and the other for percent light transmission running from 0 to 100. Note that this is only the gage, there is no included sensor or other equipment. On the back are mounting screws arranged in a rectangle about 4" by 3.5" and two threaded pegs for the signal current. A label indicates that this is an API Instruments code number 5269 model number 1066 shielded meter.
