Features: Portable Size: This handheld nuclear radiation and electromagnetic radiation detector is portable in size and easy to carry, so you can put it in your bag and take it with you and grip it for use. 2.8 Inch TFT Display: This nuclear radiation detector features a 16bit 2.8inch large TFT color display screen, multiple units display and real time curve drawing that 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, and 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 after the sensors added energy compensation. Easy to Operate: The instrument features a G-M counting tube that enjoys a high flexibility and can measure the environmental backgrounds. The dose rate is measured in real-time, the cumulative dose and the AVG dose are displayed simultaneously, and it has a calibration function. Multifunctional Design: The alarm value can be set by user, it will promote an alarm sound when over the limit ranges, and timely alarm to ensure safety use. Multiple Settings Design: Support for the setting of time, language, alarm value, record interval, quotations, timing shutdown, cumulative clear, version information. Lithium Battery: Built-in 1000mAh large capacity rechargeable lithium battery, low consumption and support for repeat use, economical and practical. 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.
