GC-03 is a multifunctional detector, a professional instrument for measuring nuclear radiation, mainly used in various occasions such as home, office, outdoor environment, etc. It uses a 2.4-inch high-definition color screen and supports real-time monitoring of NR/EF/MF.
Key Features:
1. Real-time measurement and alarm function:
The device continuously monitors and displays the measured values of NR/EF/MF and their corresponding units. And evaluates the danger level according to the alarm threshold set for each measured value.
2.Flexible radiation unit settings
The device allows users to select the NR measurement unit. Available units include μs v/h, uGy/h, mR/h, CPS, CPM, etc.
This function ensures that users can choose the most appropriate unit based on their specific measurement needs and industry standards.
3. Alarm record display function:
The alarm record page displays the alarm records in sequence, with the serial number increasing from the oldest to the latest. Each record contains the type of data that triggered the alarm (for example, NR/EF/MF) and the specific date and time when the alarm was triggered.
4 Various alarm modes
This area is highlighted, indicating that the alarm mode setting is entered and the corresponding setting content is displayed. There are three alarm modes: indicator light, vibration, and volume alarm. The three can be matched with each other and selected according to the user's wishes.

Carlo Waelchi It seems functional to me, I have no reference, but the indicators pointed to more activity in the granites, which is somewhat expected. Functional product, I would buy again. I still want to observe the battery life.

Ramiro Hayes Detects my uranium glass collection just fine. I was also able to see that an electric stove emits a lot of emf. Cool tool, seems pretty sensitive as i can see a difference between background radiation inside vs outside. I have no way to test accuracy or calibration, but i am confident that it detects radiation.
