[Geiger-Counter] The -886A nuclear radiation meter features an energy compensation tube detector to enhance sensitivity for radiation detection. Designed to accurately detect ionizing radiation intensity, including beta particles, gamma rays, and x-rays within the energy range of 48keV-1.5MeV 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 current radiation levels, maximum values, and average values across different locations. The built-in dose alarm allows users to set customizable thresholds for accurate and dependable readings. [Flexible Unit Conversion] This advanced nuclear radiation meter includes five selectable dosage units: Sv/h, Gy/h, mR/h, and cpm. Capable of detecting various types of radiation such as gamma rays, x-rays, and beta particles, it serves as a comprehensive tool for multiple radiation detection applications. [Intelligent Alarm System] Equipped with a three-mode alert system—visual, vibration, and ble—the -886A nuclear radiation meter notifies users under varying conditions. Users can adjust both current and cumulative dose alarm thresholds and reset the cumulative dose through the settings menu for personalized operation. [Broad Application Spectrum] Suitable for use in nuclear power plants, geological surveys, radiology departments, and home environments, this radiation meter effectively detects ionizing radiation and displays dose levels. Ideal for diverse settings including industrial facilities, laboratories, mining sites, and inspection vehicles.
