Geiger counter nuclear radiation detector with GM tube, dosimeter for beta, gamma, and X-ray radiation, 1100mAh, LCD screen.

A nuclear radiation detector with a Geiger-Müller (GM) tube is a sensitive device designed to detect X-ray, gamma, and beta radiation in the environment. This Geiger counter features high sensitivity and real-time readings on the HD LCD screen. It is compact and powered by a rechargeable 1100mAh battery, making it suitable for both professionals and enthusiasts who monitor radiation levels in the field.

Geiger counter - key features.

• High sensitivity – The energy-compensated GM tube detects even the smallest amount of radiation, ensuring accurate measurements.
• HD LCD screen – Clearly displays data, allows you to select measurement units, and set alarm parameters.
• Multiple alarm modes. – You can choose a light, vibration, or sound alarm as needed.
• Automatic data saving. When the device is turned off, the data is saved automatically and does not need to be re-entered.
• 5 measurement units — can be switched between μSv/h, μGy/h, mR/h, CPS, and CPM, adapting to various needs.
• Real-time clock and date — is displayed along with average and maximum values in a graphical format.
