Product Description
The Model YD-8015E X-γ Radiation Detector employs a Geiger-Müller (GM) D as its detector, offering high sensitivity, stable counting performance and a wide measurement range, enabling accurate measurement of γ and X-ray radiation. It features a high-speed microprocessor and a 2.0-inch TFT colour LCD display, combined with silicone rubber push-buttons for enhanced ease of operation. All technical specifications of the instrument have been verified through metrology laboratory testing. The instrument is widely applicable to radiation environment and radiation protection measurement in a broad range of settings, including household decoration radiation assessment, medical institutions, disease control and prevention (CDC) agencies, environmental protection, metallurgy, petroleum, chemical industry, radiological laboratories, radiation processing, mining, and various other contexts requiring radiation monitoring.
