Effective Radioactive Tester: The Nuclear Radiation Detector has the characteristics of rapid response and a wide measurement range. It can display the dose equivalent rate and cumulative dose in the working area, and mainly monitor the X, r, and hard beta radiation. Practical and Useful: The Nuclear Radiation Tester responds quickly to radiation in high-risk environments with timely alarms. The instrument is highly flexible and can measure the environmental background. Convenient to Use: The Radioactive Monitor is compact and easy to operate for beginners, the elderly, or older people. The data is stored permanently after the electricity is applied. Intelligent Protection: You can access the alarm setting options to set the alarm accumulation value and the dose rate alarm value. The nuclear radiation dosimeter automatically beeps when the radiation value exceeds the set value. Various Use: Radiation Testers are used for surrounding environment monitoring such as nuclear power plants, accelerators, steel industry, chemicals industry, isotope applications, industrial fault detection.
