The FNIRSI® GC-01 Nuclear Radiation Detector is a high-precision Geiger-Müller counter designed for the accurate detection of γ-rays, X-rays, and β-rays. Featuring a wide detection energy range (48keV–1.5MeV), real-time monitoring, and multi-alarm modes (light, vibration, sound), this device ensures reliable radiation safety measurements for professional, industrial, and personal use.

Equipped with an energy-compensated GM tube, the GC-01 provides accurate measurement of dose equivalent rates (0.00–10,000 μSv/h) and cumulative dose equivalents (0.00μSv–500.0mSv). Its multifunctional LCD interface supports unit switching (μSv/h, μGy/h, mR/h, CPS, CPM) and bilingual operation (Chinese/English).

With its compact size (120×78×27mm), long-lasting 1100mAh lithium battery, and robust design, the FNIRSI GC-01 is a versatile radiation detection instrument suitable for food inspection, building material testing, nuclear industry monitoring, and medical equipment safety checks.

Features:

• Multi-Radiation Detection – Detects γ-ray, X-ray, and β-ray radiation with high precision.

• Wide Energy Range – Detects radiation from 48keV to 1.5MeV (±30% accuracy for 137Cs).

• Accurate Dose Measurement –

  • Dose equivalent rate: 0.00–10,000 μSv/h (10 mSv/h max)

  • Cumulative dose equivalent: 0.00μSv–500.0mSv
