• Intelligent Alarm: Supports current dose and cumulative dose alarm value setting. Whether in sleep or working mode, if radiation dose exceeds the threshold, it will automatically alarm, with light, vibration, and sound alarm modes.
• Counter Tube: This radiation detector uses energy compensation counter tube to detect the strength of ionizing radiation (β particles, γ rays and X rays), improves low energy response.
• LCD Display: The radiation dose monitor is a handheld design that is easy to operate and carry, equipped with a LCD display, clear and intuitive, and can be connected to electronic devices.
• Applications: Widely used in environments with ionizing radiation, such as home improvement radiation, geological survey, inspection vehicle, nuclear power plant, industrial application, radiology, laboratory, etc.
• Working Principle: Using a gas tube or small chamber as a probe, when the voltage applied to the probe reaches a certain range, a pair of ions are generated and amplified to generate electrical pulses of the same size.
