Product description
The FNIRSI GC-03 is a multifunctional 3-in-1 dosimeter and electromagnetic field (EMF) tester. It combines the detection of nuclear radiation with the measurement of electric and magnetic fields.
Product specifications: - Measurement of three types of radiation in a single device: the detector allows simultaneous measurement of three different types of radiation – ionising nuclear radiation (?, X and ß radiation), electric field strength and magnetic field strength. Thanks to this combination, the Fnirsi GC-03 is an ideal tool, for example, when checking domestic electrical appliances, the working environment, whilst travelling, or in the vicinity of potentially hazardous equipment such as microwave ovens, distribution boxes, or even when checking food and imports from high-risk areas – highly sensitive GM tube and precise radiation detection:
at the heart of the device is an energy-compensated Geiger-Müller tube, which ensures reliable detection of ionising radiation with high accuracy and a fast response. Measurements are taken in real time, with the option to monitor both the instantaneous dose rate (ranging from 0.00 to 10,000 µSv/h) and the cumulative dose (up to 500.0 mSv). The device supports various display units, including µSv/h, mR/h or cpm, which will be appreciated not only by experts but also by ordinary users when carrying out indicative measurements - measurement history logging and alarm functions:
a major benefit is the ability to record up to 50 alarm events, which allows users to monitor trends in radiation exposure over time. Everything is clearly displayed on a 2.4-inch colour screen, which shows both current readings and the history of recorded data. If the set limits are exceeded, one or more of the preset alarms – visual, audible or vibrating – are triggered automatically. Setting the limit values is entirely up to the user, allowing the device to be adapted to a specific workplace or domestic environment.
Technical specifications: - Types of radiation detected: Nuclear (including X-rays), electric field, magnetic field. - Sensor (nuclear): Energy-compensated Geiger–Müller tube.
- Measurement range (nuclear): 0.01 µSv/h – 999.99 µSv/h (cumulative dose up to 500 mSv). - EMF range:
electric field: 1 V/m – 1999 V/m magnetic field: 0.01 µT – 99.99 µT. - Display: 2.4" high-resolution colour LCD.
- Power supply: built-in 1500 mAh lithium battery (charged via USB-C). - Alarm modes: audible, visual (light) and vibration.
