[Geiger Counter] The -886A nuclear radiation meter enhances standard radiation detection with an energy compensation tube detector to improve sensitivity. Specifically designed to accurately detect ionizing radiation intensity, including beta particles, gamma rays, and x-rays within the energy range of 48 keV to 1.5 MeV (less than or equal to 30% for 137Cs), it provides reliable radiation measurement. [Multifunctional Nuclear Radiation Meter] In addition to measuring radiation intensity, this device also monitors temperature and humidity. It displays the current radiation value, maximum value, and average value across different geographical areas. The integrated dose alarm allows users to set custom thresholds for accurate and reliable readings. [Flexible Unit Conversion] This advanced nuclear radiation meter features 5 built-in dosage units: Sv/h, Gy/h, mR/h, and cpm, which are easily switchable. Capable of detecting gamma rays, x-rays, and beta rays, it serves as a comprehensive tool for various radiation detection needs. [Intelligent Alarm System] Equipped with a three-mode alarm system—visual (light), vibration, and ble—the -886A nuclear radiation meter alerts users in different scenarios. Users can adjust both current and cumulative dose alarm thresholds and reset the cumulative dose through the settings menu for a personalized experience. [Broad Application Spectrum] Suitable for use in nuclear power plants, geological surveys, radiology departments, and home radiation testing, this meter is ideal for detecting ionizing radiation and displaying dose levels. It is appropriate for a wide range of environments, including industrial facilities, radiation laboratories, mining sites, and inspection vehicles.
