Structurally, the training unit consists of an experimental equipment and control-measuring unit.
The unit is an aluminum foundation with a light source and a vacuum photocell in an opaque casing mounted on it.
Control and measuring unit, which is included in delivery set, allows the user to adjust the intensity of the light source radiation, manage and measure the vacuum photocell anode voltage within the range of 0 … 100 V, measure the photocell current.
The stand is accompanied with a set of teaching materials and technical documentation intended for the teaching staff.
