1. HIGH SENSITIVITY: Nuclear radiation detector uses professional geiger counters as the core sensors, which can accurately detect β, γ and X , updated every second.2. AUDIBLE AND VISUAL ALARM: Whether in sleep or working state, when the detected radiation dose exceeds the alarm threshold, the geiger counter dosimeter will emit an audible and screen alarm. Take full care of your and your family's health.3. LOW POWER CONSUMPTION: Equipped with a powerful rechargeable lithium battery of 1000mAh, the nuclear radiation detector only needs to be charged for 2 to 3 hours, and the display screen can continue to measure continuously for 50 hours after automatic sleep during operation.4. PEN CLIP DESIGN: Geiger counter is as small and convenient as a pen, and you can clip it anywhere you want. This radiation detector can provide you with 24 hour comprehensive detection.5. WIDELY USED: Radiation tester can be used in home decoration radiation, irradiation processing enterprises, health and epidemic prevention, radiation therapy, nuclear laboratories, nuclear power plants, export commodity inspection, building materials, petrochemical industry, geological survey, waste steel, industrial non destructive testing, and other environments with ionizing radiation.Spec:Item Type: Geiger CounterMaterial: ABSMode: HFS 01Language: Chinese, English, Japanese, Korean, Germany, France, Spain, ItalyBattery Type: 3.7V lithium battery 1000Mah x 1 (shipped with built in battery)Charging: TYPE C, 5V 1AAlarm Type: Sound, screen flashFull Power Working Time: 10 hoursCurrent Dose Rate: 0.00 to 1000uSv/h (10mSv/h)Detection Types: β, γ and X raysScreen: 1.75 inches, color screenDetector: Energy compensation Geiger technology tube1.
