Features: 1. RG1100 personal X-Y radiation alarm dosimeter is a small high-sensitivity personal radiation dose alarm. The instrument uses G-M counter tube as a detector. 2. Using strong single-chip technology and has a strong anti-interference ability. Mainly used to monitor the X-ray and Y-ray. 3. In the measurement range, can be arbitrarily set alarm threshold, when the alarm threshold is reached, an alarm to alert the staff in time to pay attention to safety. 4. Widely used in radiation processing enterprises, health and epidemic prevention, radiation therapy, nuclear laboratories, nuclear power plants, import and export commodity inspection, building materials, petrochemicals, geological survey, scrap steel, industrial nondestructive flaw detection ionization Radiation environment, personal radiation dose monitoring and protection. 5. Using energy compensation GM tube, indicating the value of accurate, fast response, in a leading position. 6. High-end OLED display, English interface, the dose rate LED strobe instructions, simple and clear. 7. Dose rate, cumulative dose, blocking fault alarm function, sound, light, vibration alarm any combination. 8. The alarm threshold is set arbitrarily within the range. 9. The alarm data is automatically stored for easy query. 10. Optional intelligent wireless networking, to achieve personal dose centralized management.
