This is a kind of fine quality geiger counter, which can help detect γ, β, X rays. High detection sensitivity, especially for environmental radioactivity monitoring to detect traces of nuclear radiation. Interference resistance ability, capable of reliable operation in complex electromagnetic environments. Widely used, can be used in the home environment, daily necessities, mineral rocks, decorated stone and other radioactive detection, can also be used for industrial or radioactive leakage detection of imaging equipment. You can have a try.

Features:
Handhold instrument design, built-in rechargeable batt-ery for easy to carry around with you.
Multifunctional design, it can be used to detect the γ, β and X(electromagnetic wave) rays.
Multiple working modes design, M1: usv/h (mute) , M2: usv/h (beep), M3: CPM (mute) , M4: CPM(beep).
With alarm function, it will alarm when the radiation is over threshold, the threshold can be set, and also support turn off alarm.
Default: M1F1, turn off led background light after one minute, and turn on Led with press of any button.
Onboard TFT color screen, easy operation, microcomputer automatic controls, convenient to use.
Large exploring tube design, with detection sensitivity, especially for environmental radioactivity monitoring to detect traces of nuclear radiation.
You can quickly determine the radiation situation surrounding environment, to quickly locate the exact location of radiation sources.
Interference resistance ability, capable of reliable operation in complex electromagnetic environments.
Wide applications, can be used in the home environment, daily necessities, mineral rocks, decorated stone and other radioactive detection.
