FNIRSI GC-03WT Multifunctional Ionizing Radiation Detector

The FNIRSI GC-03WT is a compact, multifunctional ionizing radiation detector that combines a Geiger counter with electric and magnetic field measurement in one handheld device. Featuring an energy-compensated Geiger-Müller tube, it provides accurate detection of gamma radiation from 0.01 to 10,000 μSv/h with high sensitivity (80 CPM/μSv). The large 2.4-inch color TFT display shows real-time data in multiple units (μSv/h, μGy/h, mR/h, CPS, CPM) and includes a dynamic graph mode for trend analysis.

• 3-in-1 measurement: ionizing radiation, electric field (V/m), and magnetic field (μT) – replaces multiple devices
• Triple alarm system: audible, vibration, and visual LED alerts with configurable thresholds
• Data logging: records up to 50 alarm events for history review
• Three display modes: quick view, professional, and curve mode for flexible data analysis
• Day/night screen: adjustable backlight ensures readability in any light
• Portable design: compact (138×63×32 mm) and lightweight (~141 g) with intuitive rotary knob control

Ideal for home users, professionals, and hobbyists who want to monitor environmental radiation and electromagnetic fields. Powered by a built-in rechargeable lithium battery for cordless operation.
