Geiger Counter Nuclear Radiation Detector – Portable Ionizing Radiation Tester

Geiger Counter Nuclear Radiation Detector – Portable Ionizing Radiation Tester

Stay safe in uncertain environments with this Nuclear Radiation Detector, a compact and highly sensitive Geiger counter designed to detect beta (β), gamma (γ), and X-ray radiation. Utilizing a high-precision energy-compensated GM tube, this radiation tester delivers accurate real-time measurements for environmental monitoring, laboratory use, or personal safety.

With a sensitivity of 80cpm/μSv (Co-60) and a wide measurement range from 00.00 to 99.99 μSv/h, the device provides reliable radiation monitoring for professionals and hobbyists alike. You can set alarm thresholds at 0.5, 1.0, 2.0, or 5.0 μSv/h, and choose between audible particle detection, alarm sound, or silent mode—ideal for different working conditions.

Housed in durable ABS engineering plastic, the unit is portable at just 180g (excluding batteries) and measures 135×70×38mm. It operates in harsh conditions from -25°C to +45°C with humidity up to 95%, and supports multiple power options: AA dry batteries, rechargeable batteries, or USB—making it perfect for fieldwork, emergency response, or education. Whether you're monitoring radioactive zones or ensuring the safety of imported materials, this radiation tester is an essential tool for radiation awareness and protection.
