This new version of the Photo Electric Effect comes with 2 built-in separate meters.  One displays the current through the Photo Tube in 0.1 nanoamps and the other displays the backing volts that brings the current to exactly zero.   With both readings on view without the need for switching,  experiments are faster and less confusing.

The light source is by LEDs which are selectable from the front panel.

The unit is powered by a 12V.AC or DC plug pak (not supplied).  Instructions and experiment sheets included.  Made in Australia.
