1.The measurement accuracy is high. For typical samples, the response time is generally within 1 to 3 seconds.
2. High-definition large screen, intelligent, accurate and stable;
3. The measurement interface is preset with common isotopes, allowing for smooth switching and easy operation.
4.Compatibility with common radionuclides: Supports therapeutic radionuclides widely used in nuclear medicine including Samarium-153, Yttrium-90, Iodine-131, Phosphorus-32, as well as positron-emission diagnostic radiopharmaceuticals such as Fluorine-18, Carbon-11, Oxygen-15, Nitrogen-13, Gallium-68, etc.
5.A dedicated syringe holder is configured, enabling the measurement of implanted 125I seed sources.
6. It is equipped with nearly a hundred common isotopes and supports the addition of new isotopes, meeting the application needs of users in various scenarios.
7. It can be externally connected to a dedicated printer to output the measurement report of the nuclide activity.(optional).
8.One-click bilingual switching: The main control system supports one-click switching between Chinese and English operation interfaces for efficient and convenient use.
