Features High Sensitivity Detection: Equipped with a GM counter sensor, this device accurately detects X, γ, and β rays, ensuring safety without compromising its integrity Real-Time Data Display: The 2.0-inch TFT color screen provides immediate access to instantaneous, average, and cumulative radiation values, enhancing user awareness Customizable Alarm System: Featuring both sound and light alerts, users can easily set their own radiation detection thresholds for tailored safety notifications Long Battery Life: With a built-in large capacity battery, enjoy up to 14 days Features: 1、High Sensitivity: The nuclear radiation detector uses high sensitivity counter detection technology with an accuracy of 0.01μSv/h. The nuclear radiation dosimeter detects β, X and γ rays radiation and will automatically sound an alarm when the radiation level exceeds 0.5μSv/h. 2、Realtime Monitoring: Large backlit LCD screen, which can be seen clearly even in dark places. Realtime values and average values can be displayed on the screen, and you can also view a trend graph of realtime data changes. 3、Lightweight: You can put this lightly designed radiation detector in your bag and carry it anywhere. With a bracket on the back, it is easy to install the nuclear radiation detector and observe the data. 4、USB Charging: This nuclear radiation detector has a large capacity 2500mAh battery with a power consumption of only 0.25W. Equipped with a USB charging cable, it can detect immediately after power on, without calibration and with clear and intuitive data. 5、Wide Apply: The detector is suitable for home radiation, irradiation procing, enterprises, health, radioactive treatment, nuclear laboratories, nuclear power plants, export commodity inspection, building materials and other situations.
