1. Intelligent alarm: Support setting alarm values ​​for current dose and cumulative dose. Whether in sleep mode or work mode, if the radiation dose exceeds the threshold, it will automatically alert you with light, vibration, and sound alarm modes.
2. Geiger Counter Tube: This radiation detector uses an energy-compensated Geiger counter tube to detect the intensity of ionizing radiation (beta particles, gamma rays, X-rays) and improves low-energy response.
3. Working principle: A gas tube or a small chamber is used as a probe, and when the voltage applied to the probe reaches a certain range, a pair of ions are generated and amplified, producing an electrical pulse of the same size.
4. Portable Design: The radiation dose monitor has a handheld design, easy to operate and carry, with LCD display, clear and intuitive, and can be connected to electronic devices.
5. Applicable fields: Widely used in environments with ionizing radiation, such as home renovation radiation, geological surveys, inspection vehicles, nuclear power plants, industrial applications, radiology, laboratories, etc.
