The FNIRSI GC-01 is a compact and precise Geiger counter that enables real-time monitoring of ionizing radiation. The device has a large LCD screen with a graphic radiation level graph, a sensitive Geiger-Müller counter and an alarm function (sound, light and vibration) when the set value is exceeded. The device is useful for detecting radiation in food, metals, construction materials, industrial equipment, and in X-ray and CT diagnostics. You can charge the 1100 mAh battery via the USB-C port.
The LCD screen provides a clear and real-time view of the detected radiation, so you can quickly react when acceptable levels are exceeded. With the help of the graphic diagram, you can easily observe the changes in the environment. The measurement units (nSv/h, pGy/h, mR/h, cps, cpm), alarm settings, backlight and language can be selected.
The Geiger-Müller counter detects beta, gamma and X-ray radiation, which enables more accurate measurements in both industrial and domestic environments. The technology used also makes it possible to record very low radiation doses.
The device measures radiation in the range from 0.01 µSv/h to 10,000 µSv/h, which enables the detection of not only background radiation, but also much higher levels harmful to health. The measured cumulative dose reaches 500.0 mSv.
The FNIRSI GC-01 meter performs well in household, medical, industrial and defense applications. It can be used to monitor radiation in marble, cosmetics, imported products, hospitals, nuclear power plants, metallurgical plants, and by travelers and healthcare providers. The non-slip silicone housing is drop-resistant, so the device is easy to use in the field and in harsh conditions. The 1100 mAh battery provides up to 10 hours of continuous use, and charging via the USB-C port makes everyday use easier.
