SPECIFICATIONSAlarm method: light, vibration, soundBattery Included: YesBrand Name: FNIRSICertification: CECumulative dose equivalent: 0.00μSv-500.0mSvDetector: Energy Compensation GM tube (Geiger Technology tube )Dosage unit: μSv/h,μGy/h,mR/h,cps,cpm SwitchDose equivalent rate: 0.00-10000uSv/h (10mSv/h)Energy range: 48keV-1.5Mev≤±30% (for 137Cs-)Fnirsi Model: GC-01High-concerned chemical: NoneLanguage: Chinese/English switchOrigin: Mainland ChinaPower supply: 1100mAh lithium batteryProduct name: Nuclear radiation detectorSensitivity: 80CPM/uSv (For Co-60)Types of detection rays: y-ray, x-ray,B-ray The FNIRSI GC-01 nuclear radiation detector uses a higher-precision Geiger-Miller counter. Counter for detecting the intensity of ionizing radiation (beta particles, gamma rays and x-rays). Use a gas tube or a small chamber as a probe.When the voltage applied to the probe reaches a certain range.Each time the ray is ionized in the tube to produce a pair of ions, it can be amplified to produce an electric pulse of the same size.And recorded by the connected electronic device.The number of rays per unit time thus measured.The alarm threshold measurement rate can be arbitrarily selected.
