Gossen Labosix enlarger exposure meter.

The Gossen Labosix is an exposure meter to be used in the darkroom for enlarging purposes. The sensor contains a CdS light sensitive device with a small hole and is very useful for spot measurement. On the left side you will find the on/off switch and also the scale illumination control. With the meter comes a special test negative used for calibrating the meter.

The test negative is a step wedge, devided into six squares with different density and about 0.15 D step. On top of the meter is a knob which can be turned and also a scale. This scale functions as a film speed index.
