The FNIRSI GC-03 WT multifunction detector measures ionizing radiation as well as the strength of electric and magnetic fields. It uses an energy-compensated Geiger-Müller tube and features a 2.4-inch color display with adjustable backlighting and day and night modes. Three display views—quick, professional and graphical—let you monitor measurements and changes at a glance.
The dynamic graph shows changes in radiation in real time, while up to 50 recent alarm events are stored. The alert system includes an audible signal, vibration and LED indicators, with adjustable alarm thresholds. The device is operated using a rotary knob, and its built-in battery charges via USB-C. The device also supports software updates.
