1. Professional and High Sensitivity: Fellat nuclear radiation detector adopts high-sensitivity GM detection technology, the accuracy is as high as 0.01 Sv/h, 80cpm/Sv/(Co-60). The nuclear radiation dosimeter includes Beta (), Gamma () and X-ray radiation detection. When the radiation level exceeds 0.5Sv/h, it will automatically alarm. 2. Multifunctional GEIGER counter: real-time value and average value can be displayed on the screen, so you can view them at the same time. Real-time detection of data per second, and real-time viewing of radiation trends. The Fellat Geiger Counter is equipped with a large LCD display, so you don't have to worry about it even in a dark place. 3.USB powered or battery powered: Radiation detector with type-c cable, you can use the charging cable without using the battery, just plug it into the socket to start detecting. You can also use 3 AAA batteries. Two types of power supplies can meet your different needs. (battery not included) 4. Lightweight and easy to use: This portable dosimeter has a lightweight design, you can put this radiation detector in your bag and carry it anywhere. The Geiger counter is easy to use, it can be measured immediately when it is turned on, no calibration is required, the data is clear and clear, and the elderly can easily use it. 5. Wide application: Radiation dosimeter detectors can be used to detect/monitor/measure indoor or outdoor low-dose background environments, and are widely used in home improvement radiation detection, irradiation processing enterprises, laboratories, geological surveys, etc., where ionizing radiation exists.
