DIY Geiger Counter Kit with OLED Display: Handheld Radiation & X-ray Tester

Description:

This Nuclear Radiation Tester is designed to detect X-rays, γ-rays, and β-rays. It can measure the radioactive dose of materials such as marble, antiques, jade, seawater products, iodine 131, medical equipment, and a variety of unknown minerals used in decoration.

Features:

• Sound and light indication for detection alerts.
• Functions include real-time dose rate, average dose rate, cumulative dose rate, and a trend chart.
• Small OLED screen for clear display of measurement results.
• Equipped with an ARM processor for fast operation and powerful processing capabilities.

Usage:

1. Place the cover tube close to the radiation source for testing.
2. Avoid touching the component area when the device is powered on to prevent electric shock; hold the device in the designated handheld area.
