The GRAETZ probe program consists of calibratable gamma probes for the equivalent dose rate Ḣ*(10), pulse probes for extending the measuring range of basic instruments, such as the dose rate measuring systems of the GRAETZ-X5C series or GammaTwin S, as well as telescope probes and NaI scintillation probes. Probes can be used in combination with a telescope to measure ionizing radiation in hard-to-reach places. Learn more about the GRAETZ probe program and the possible areas of application.
