Dr. No Geiger counter radiation detector

This compact Geiger counter is a powerful radiation detection device for identifying beta (β), gamma (γ), and X-ray radiation. It is suitable for use in nuclear medicine, the steel and chemical industries, and environmental laboratories. The dosimeter offers a wide measurement range and includes multiple alarm thresholds. Measurement data and an average value are shown on the LCD display. A user-friendly interface with intuitive button symbols and multiple settings makes operation easy. Thanks to its low power consumption, the detector is ready for long-term use. Its portable design allows the device to be used anywhere with ease.
