Scintillation Survey Meter TCS-171 & 172
Hitachi’s survey meters feature a clear and easy-to-read indicator, user-friendly control panel, and colorful, lightweight and compact design, offering outstanding precision and functionality as a survey meter. The meters are widely used in various radiation handling facilities, such as universities, laboratories, hospitals, and nuclear power plants. Choose one that best suits your needs and purposes from our extensive range of models.
The energy compensated scintillation detector is ideally suited for a wide variety of gamma measurement. The performance and liability are already evident through a lot of installation in Japan. In addition to Sv/h, TCS-171 offers Gy/h, and TCS-172 offers s-1 for your selection.
