Feature 1Memory Card: Nuclear radiation contamination detector built in memory, after power failure, the accumulated dose value, dose rate alarm threshold and dose alarm threshold and some other data are not lost. 2Multifunction: Nuclear radiation detector can be arbitrarily adjusted alarm threshold, Chinese and English switch, screen backlight, real time, dose rate curve display function, etc.. Real time detection of radiation dose rate, and at the same time record the accumulated dose value. 3Wide Application: Nuclear radiation monitor can be widely used in home radiation detection, irradiation processing enterprises, health epidemic prevention, radioactive treatment, nuclear laboratories, nuclear power plants, import and export commodity inspection, building materials, petrochemical industry, etc. 42 Power Supply Modes: The nuclear radiation detector is capable of USB plug in use and AAAx3 dry cell batteries, plug in can be used to supply power when ultra long continuous detection time is required. 5Stable Performance: Geiger counter's membrane keyboard is beautiful and novel in appearance, small in size, light in weight and strong in sealing. It is dustproof, oil proof, shockproof and has a long service life.Item Type: Nuclear Radiation DetectorMaterial: ABSWeight: Approx. 166g/5.9ozDetector: Glass Geiger CounterDose Rate Range: 0.1Sv/h-10mSv/hDose Range: 0.00Sv~10SvSensitivity: >1cps, Sv, h (Under the Condition Co60 of the Radiation Source)Energy Response: 48keV-1.5MevRelative Error: <10% (At 1mSv/h)Power Supply: 3 AAA, Dry Cell Batteries, Or USB Type C Power Supply (Shipped Without Batteries)Power Consumption: <60mWTemperature Characteristics: -10~+50Use: Nuclear Radiation Detector .wang-edit-text{ font-family:'Arial' !important; } .wang-edit-text table { border-top: 1px solid #000; border-left: 1px solid #000; } .wang-edit-text table td, .wang-edit-text table th { border-bottom: 1px solid #000; border-right: 1px solid #000; padding: 3px 5px; } .wang-edit-text table th { text-align: center; }Package List1 x Nuclear Radiation Detector1 x USB Cable1 x Screwdriver1 x Manual
