Measuring range 0.08uSv/h~9999uSv/h. 2.Multifunctional Geiger instrument: The instrument uses an energy-compensated 48mm GM Geiger counter tube as a detector, which has the characteristics of high sensitivity, strong anti-interference ability, and accurate measurement; it uses a powerful microprocessor and is equipped with TFT Display screen makes operation easier. 3.Intelligent alarm: The product itself has three alarm modes: sound, flash, and vibration, and the alarm threshold can be set arbitrarily. When the alarm threshold is reached, an alarm will be issued to remind the staff to pay attention to safety. The main technical indicators of the instrument meet international standards. 4.Lithium battery power supply: The size of the product is 16*27*105 mm. It is powered by a built-in lithium battery. It can be continuously measured for 15~24 hours when fully charged. Power-saving and durable, reusable. 5.Field of application: Widely used in environments with ionizing radiation. Applied to home decoration radiation, irradiation processing enterprises, sanitation and epidemic prevention, radiotherapy, nuclear laboratory, nuclear power plant, import and export commodity inspection, building materials, petrochemical industry, geological survey, scrap steel, industrial non-destructive flaw detection, etc. in the presence of ionizing radiation environment.
