The GMC-500 handheld nuclear radiation detector is a highly sensitive and wide range nuclear radiation detector that can detect beta, gamma, and X-rays, and can directly read the level of nuclear radiation. This dosimeter uses two combined Geiger Maitreya counting tubes to achieve wide limit monitoring of nuclear radiation dose, and can be widely used in environmental monitoring, healthcare, chemical facilities, nuclear industry, entry and exit inspection and quarantine, and other fields.

Product advantages:

1、 Using two Geiger Maitreya counter tubes to achieve wide limit monitoring;

2、 Built in beta radiation source, capable of automatic inspection of alarm channels;

3、 Mature and stable detection method: using advanced and mature Geiger tubes, combined with precision detection circuits, low-power high-voltage drive circuits, and calibratable counting algorithms, to make the product reliable and stable, with real and reliable detection results;

4、 Friendly human-machine interface, using thin film button operation and LCD screen display mode, easy to operate, comfortable to feel, and simple and clear human-machine interface;

5、 Complete data input and output interfaces, with a universal Micro USB interface used to connect the instrument to a PC and operate it through the upper computer. The standard 3.5mm audio interface is used to transmit pulse signals to other external devices.
