Geiger Counter Nuclear Radiation Detector LCD Display Beta Gamma X-ray Tester Nuclear Radiation Dosimeter 0.05uSv--50mSv

Product introduction:
1. The product is one small type high sensitivity radiation dosage alarm device, mainly used to monitor the X, β ray and γ ray. Measure range: 0.05uSv-50mSv,Measure precision: -17%...+25% based on 137Csy.
2. It has two measure methods. Real-time measure and timing measurement function, you can set the Measurement Time range from 0 to 999 hours. The Geiger counter also can be save the historical record of the recent 10 timing measurement.
3. Two alarm methods sound and flash freely assembled, and the alarm threshold able to be freely set, send out alarm and remind the workers attention at safety in time when it achieved alarm threshold.
4. Our the geiger counter has other various setting, such as delete setting, sound setting, system clock setting, sleep setting and unit setting language change,you can operate in English (default) or Chinese. Easy one-handed operation.
5. Widely applied in the environment where existing ionize radiation environment, personal accepted radiation dosage supervise and protection, such as family decoration, radiation shining manufacture enterprises, hygiene, epidemic prevention, radiation treatment, nuclear lab, nuclear station, import export commerce inspection, building materials, petroleum chemical, geology general investigation, used steels, industry flaw detection and others.
