Handheld Portable Nuclear Radiation Detector Household Laboratory Multi-function Radioactive Geiger Counter Digital TFT Color Display β-Rays X-Rays γ-Rays Tester with Alarm Function This radiation detector adopts a highly sensitive Geiger countertube, it is mainly responsible for monitoring the radiation of X, γ, and β rays in various radioactive working areas; it is characterized by fast response and wide measurement scope, and it can display the current radiation value, average and highest values over a period of time, curve graph, current alarm threshold, cumulative alarm threshold, cumulative detection values, temperature, humidity; it is widely used in the individual safety protections monitoring and radioactive indication for working personnel in the following fields: nuclear power plant, accelerator, iron & steel industry, chemical industry, isotope application, radioactive laboratory and environmental monitoring of nuclear facilities. Features: Portable Size: This handheld nuclear radiation detector is a minimalist appearance with an anti-slip design, is portable in size, and easy to carry, so you can put it in your bag and take it with you. Digital TFT Display: This nuclear radiation detector features a TFT color display screen, multiple units display, and the 4-language switchable design allows you to read the detection data clearly and easily, and you can get results in time.  Radiation Detect: The detector is used to measure X, γ, and β rays radiation, it is optimal for measuring small changes in radiation levels and has high sensitivity for most commonly used nuclides. The detection is more accurate. Real-Time Display of Values: Update real-time radiation values every second, and update average values every few minutes, more intuitively. With the current radiation value, average and highest values over a period of time, curve chart, current alarm threshold, cumulative alarm threshold, cumulative detection values, temperature, and humidity display function. Multifunctional Design: With temperature and humidity detect function. With alarm functions, the alarm value can be set by the user, it will promote an alarm sound when over the limit ranges, and timely alarm to ensure safer use.  Two Versions are Optional: You can choose the Asian version and the European version according to your demands. The Asian version supports the switch between Chinese, English, Japanese, and Korean. The European version supports the switch between English, Russian, Ukrainian, and Polish. Wide Applications: This radiation tester can be widely used in nuclear power plants, accelerators, the iron & steel industry, the chemical industry, isotope applications, radiology laboratories, and ambient monitoring of nuclear facilities.​ Specifications: Material: plastics Type: Asian version, European version (optional) Battery: 3 * 1.5V dry batteries or 3 * 1.2V rechargeable batteries (not included) Detection technology: G-M detection technology Detection Type: β，γ，X-rays，temperature and humidity Display mode: TFT screen + backlight Energy ranges: 20kev~3.0mev ≤±30%(137Cs-) Sensitivity: 80cpm/μSv/(Co-60) Test accuracy: 0.01 μSv/h Real-time ranges: 0-99.99 μSv/h Accumulation ranges: 0-99.999 mSv/h Real-time error: ≤10% Mean error: ≤3% Item size: 105 * 70 * 30mm / 4.13 * 2.76 * 1.18in Package size: 140 * 110 * 61mm / 5.51 * 4.33 * 2.40in Package weight: 220g / 7.76ounce Packing List: 1 * Radiation Detector
