FNIRSI GC-03 WT is the white housing variant of the multifunctional 3-in-1 radiation detector. It adopts an energy-compensated GM Geiger-Müller tube to detect ionizing radiation including γ, X and hard β rays. It simultaneously measures nuclear radiation dose rate, cumulative dose, electric field strength and magnetic field strength. Equipped with a 2.4-inch adjustable-backlight color screen and real-time data trend curve. Three alarm modes: sound, vibration and light. It stores up to 50 alarm records and supports multiple dose unit switching (μSv/h, μGy/h, mR/h, CPS, CPM). Built-in 1500mAh rechargeable lithium battery with Type-C charging, bilingual English/Chinese menu. Widely used for home safety inspection, marble/stone testing, medical radiation screening, household appliance EMF checking, seafood and cargo radioactive contamination inspection, field environmental monitoring.
