The radioactivity meter is a useful tool to examine solar cells for their characteristics. With a DC voltage range of 0… 60V and a DC current range of 0… 12 A, the radioactivity meter covers a large number of solar modules. The determined characteristic curves are saved directly on the solar module tester. Up to 100 measurements can be stored in the data memory of the radioactivity meter. The stored measured values ​​can then be read out and further processed on a PC with the associated software. In addition, it is possible to operate the radioactivity meter completely via the software.

The radioactivity meter has two different measuring functions for determining the characteristics of a solar module. In the automatic mode, the characteristic curve is created with automatic parameters by the radioactivity meter. This gives the operator a first impression of the state of the solar module. In manual mode, the start and end of the current value can be set on the radioactivity meter. If the area of ​​the solar module and the power of the incoming radiation are stored in W/m², the radioactivity meter can calculate the efficiency and the fill factor of the cell. Another measuring function with the solar module tester is the one-point measurement. A specific current can be controlled and checked by the radioactivity meter.

The LCD display of the radioactivity meter has a size of 4.8“. This means that the characteristic curve and all measured values ​​can be read off at the same time. In order to analyze the characteristic curve better, each individual measuring point on the radioactivity meter can be approached. For a different view of the X and Y axes, you can switch between current, voltage and power by pressing a button on the radioactivity meter.

Because of its many different functions, the radioactivity meter is the ideal measuring device to examine solar modules for their effectiveness. The radiation detector is therefore used in radioactivity systems and research facilities for the further development of solar modules. The radiation detector can optionally be equipped with an ISO calibration certificate.
