## Summary description

The FNIRSI GC-01 Geiger meter features a digital LCD display, powered by a lithium battery. Its compact size makes it portable and easy to use for measuring radiation levels. Ideal for safety monitoring in various environments.

## Long description

The FNIRSI GC-01 is a compact Geiger counter with a built-in GM tube for detecting ionizing radiation including gamma rays, beta particles and X‑rays. It provides cumulative dose equivalent readings from 0.00 µSv up to 500.0 mSv and displays measured values on an LCD. The device supports alarm threshold settings for both current dose rate and accumulated dose, and offers selectable combined alarm modes (light, vibration and sound). The instrument is battery powered and designed for portable, one‑hand operation.
Advantages
The GC-01 uses a Geiger–Müller tube to provide pulse counting of ionizing events and reports dose-related values within the specified energy range. It allows configurable alarms for immediate notification when dose rate or total accumulated dose exceeds preset limits. The unit includes settings for time, measurement units and language, and its lightweight, handheld form factor makes it suitable for field use.
Suitable for
Home renovation and radon/radiation checks
Geological and field surveys
Industrial and plant inspections
Medical radiology departments and laboratories
Vehicle and equipment screening
Key specifications
Detected radiation types: gamma, beta, X‑rays
Cumulative dose equivalent range: 0.00 µSv – 500.0 mSv
Energy response range: 48 keV – 1.5 MeV (±30% at 137Cs γ)
Alarm modes: light, vibration, sound (combined selectable)
Display: digital LCD
Probe type: Geiger–Müller tube (gas tube / small chamber)
Operation: handheld, one‑hand operation
How to use
Power on the device and allow the GM tube to stabilise. Use the menu to set the system clock, preferred measurement units and language. Set the desired alarm thresholds for current dose rate and accumulated dose; when the measured radiation exceeds these thresholds the device will trigger the selected alarm mode (light, vibration and/or sound) whether the screen is active or in sleep mode. Hold the meter with the probe pointed toward the area to be measured and read the dose rate and cumulative dose values on the LCD.
Usage recommendations
The FNIRSI GC-01 is intended for general radiation monitoring and screening. For precise dose estimation in regulated or clinical contexts, use a calibrated, application‑specific instrument and follow local safety standards. Avoid exposing the GM tube to strong mechanical shock or moisture, and replace batteries as indicated to ensure reliable operation.
