GC-03 is a multifunctional detector, a professional instrument for measuring NR, 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 particle, electric field strength and magnetic field strength and their corresponding units. And evaluates the danger level according to the alarm threshold set for each measured value.
2.Flexible particle unit settings
The device allows users to select the particle measurement unit. Available units include us 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.
