FNIRSI GC-03 Geiger counter for measuring radioactivity

Radiation detector, FNIRSI GC-03 dosimeter. The FNIRSI GC-03 is a multifunctional 3-in-1 dosimeter and electromagnetic field (EMF) tester. The GC-03 is a multifunctional radiation detector, a professional instrument for measuring nuclear radiation, used primarily in various environments such as the home, office, car, outdoors, etc. It features a 2.4-inch high-resolution colour display and supports real-time monitoring of nuclear radiation, electric field strength, magnetic field strength, etc. The meter supports three alarm modes: audible, vibration and visual.


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 boards, or even when checking food and imports from high-risk areas

– a highly sensitive Geiger tube and accurate 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 taking indicative measurements

- Measurement history logging and alarm functions: a major advantage is the ability to log 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 automatically triggered. Setting the limit values is entirely up to the user, allowing the device to be adapted to a specific workplace or domestic environment. - Three types of alarms: visual, audible and vibrating alerts with adjustable threshold values
- Long battery life: 1500 mAh battery for extended and reliable use in the field - Combines nuclear radiation detection with the measurement of electric and magnetic fields
