Feature:1. MULTI FUNCTIONAL GEIGER COUNTER: Our Geiger counter has various settings, such as alarm settings, system clock settings, unit settings, and language change. You can operate it in English (default), Chinese, or Japanese. It is easy to operate with just one hand.2. RADIATION DETECTOR: Geiger counter is a radiation detector with a built in GM sensor. It has quick response time and high accuracy, capable of detecting gamma, beta, and X rays. It measures cumulative dose equivalent from 000.00999.99uSv/h (1mSv/h). Energy range of 48keV1.5Mev<30%(for 137Cs).3. INTELLIGENT ALARM: In the alarm setting option, you can set the current dose alarm value and cumulative dose alarm value. The radiation monitor will automatically alarm when the detected radiation dose exceeds the threshold, whether the detector screen is in sleep mode or working mode. It offers three combinations of alarm modes, light, vibration, and sound.4. APPLICATION FIELDS: Widely used in environments with ionizing radiation, such as home radiation assessment, geological surveys, transportation inspections, nuclear power plants, industries, radiology departments, and radiology laboratories.5. WORKING PRINCIPLE: AIR 09 uses a GM counter. It is used to detect the strength of ionizing radiation (beta particles, gamma rays, and X rays). It uses a gas filled tube or small cavity chamber as a probe. When the voltage applied to the probe reaches a certain range, every time a radiation particle ionizes in the tube to produce a pair of ions, it can be amplified to generate an equal sized electrical pulse. This pulse is then recorded by connected electronic devices. The radiation count per unit time is measured based on this.Specification:Item Type: Nuclear Radiation DetectorMaterial: ABS 1.
