Fnirsi GC-03 - multifunctional radiation detector (black)

Description

FNIRSI GC-03 is a multifunctional radiation detector that combines measurement functions for nuclear radiation, electric fields, and magnetic fields. The device features a 2.4-inch color display with adjustable brightness, ensuring clear real-time results.

Equipped with a precise Geiger-Müller tube (J321/M4011), the detector provides high sensitivity, low power consumption, and accurate measurements across a wide range. It is suitable for various environments – from home and office use to professional applications in industry, laboratories, or food safety inspections. The GC-03 supports three alarm modes: light, sound, and vibration, and allows users to set custom warning thresholds. With the Dynamic Curve Mode function, users can monitor radiation level changes as real-time graphs, and the device stores up to 50 alarm records. Supported radiation types include γ, X, and hard β, allowing full monitoring of potential hazards.

The detector is useful in environmental monitoring, work near nuclear power plants, medical diagnostics (e.g., CT), and assessing the safety of everyday devices such as microwave ovens, laptops, refrigerators, or washing machines. Lightweight and portable, it weighs only about 141 g, and its compact size makes it convenient to carry. The built-in 1500 mAh battery ensures long-lasting operation, making it a reliable companion for fieldwork and mobile use. With simple operation via a rotary dial, the GC-03 is intuitive for both beginners and professionals.
