Introduction to Portable Gamma Spectrometer:

Portable gamma spectrometerIt has low power consumption, digitalization, intelligence, portability, GPS satellite positioning, and simple operation. The CNC automatic spectrum stabilization system can correct spectral line drift caused by various factors such as temperature, and can also choose to turn off self stabilization measurement. Automatically search for self stabilizing peaks and display peak position graphics. Fast, timed, and continuous measurement modes; The measurement results can be selected to display the counting rate or content, and there is a radioactive intensity sound alarm. Equipped with backlit LCD display, touch buttons, and a full Chinese menu. Parameters can be set and can store 1500 sets of measurement data; Standard USB interface.
