[Geiger Counter] The -886A nuclear radiation meter features an energy compensation tube detector to enhance sensitivity for radiation detection. Designed to accurately measure ionizing radiation intensity, including beta particles, gamma rays, and x-rays within the energy range of 48 keV to 1.5 MeV with less than or equal to 30% variation (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 locations, along with a user-settable dose alarm threshold to support accurate and personalized measurements. [Flexible Unit Conversion] This advanced nuclear radiation meter includes five built-in dosage units: Sv/h, Gy/h, mR/h, and cpm, which can be easily switched. Capable of detecting various types of radiation such as gamma rays, x-rays, and beta rays, it serves as a comprehensive tool for a wide range of radiation detection applications. [Intelligent Alarm System] Equipped with a multi-mode alarm system that activates via light, vibration, and sound, the -886A alerts users under varying conditions. Users can adjust both current and cumulative dose alarm thresholds and reset the cumulative dose through the settings menu for a tailored 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 various environments including industrial facilities, radiation laboratories, mining sites, and inspection vehicles.
