Product information

Description

The FNIRSI GC-03 BK is an advanced, user-friendly multifunctional ionizing radiation detector that integrates measurements for nuclear radiation, electric fields, and magnetic fields. Designed for both home users and professionals, this device provides high precision, rapid response times, and an intelligent alarm system, all displayed on a clear 2.4-inch color screen. It is a versatile tool for maintaining environmental awareness and safety.

Advantages

This device stands out by combining three measurement functions into one compact unit, which saves space and simplifies environmental monitoring. It utilizes an energy-compensated Geiger-Müller tube to ensure stable and reliable detection of ionizing radiation. The inclusion of a dynamic graph mode allows users to track radiation trends in real time, while the alarm history feature records up to 50 events for comprehensive data analysis. With its triple alarm system—audible, vibration, and visual—users are always alerted to potential hazards promptly. Furthermore, the device features a robust design, a long-lasting battery, and the capability for firmware updates to ensure long-term utility.

Suitable for

  • Monitoring natural background radiation levels
  • Assessing electromagnetic fields from household appliances and electronics
  • Industrial radiation safety inspections
  • Educational purposes and laboratory research
  • Personal environmental safety assessments

This device may not be suitable for high-precision scientific research requiring specialized laboratory-grade equipment or for detecting specific types of alpha radiation, as the Geiger-Müller tube is primarily optimized for gamma, X-ray, and beta radiation. It is intended for general monitoring and safety assessment rather than certified regulatory compliance testing.

Key specifications

  • Radiation measurement range: 0.00 to 10,000 μSv/h
  • Electric field range: 1 to 1999 V/m
  • Magnetic field range: 0.01 to 99.99 μT
  • Display: 2.4-inch color LCD
  • Battery: 1500 mAh rechargeable via USB-C
  • Dimensions: 138 × 63 × 32 mm
  • Weight: 141 g
  • Measurement units: μSv/h, μGy/h, mR/h, CPS, CPM

How to use

To begin, power on the device using the control knob. Navigate through the menu to select your desired operating mode, such as quick view, professional, or dynamic graph mode. The device will immediately begin monitoring the environment. You can configure custom alarm thresholds to suit your specific safety requirements. The screen provides real-time data, and the device will trigger an alert if radiation or field levels exceed your set limits. Use the USB-C port to charge the internal battery as needed.

What to consider before purchase

  • Verify that the measurement ranges meet your specific safety requirements.
  • Note that the device menu is available in English and Chinese.
  • Consider the intended environment, as this is a portable device for general monitoring.
  • Ensure you are comfortable with the operation of a rotary knob interface.
Usage recommendations: For the most accurate results, keep the device away from direct contact with high-voltage sources and ensure the sensor area is not obstructed. Regularly check for firmware updates to benefit from the latest performance improvements.
