Feature 1Compact and Lightweight: This nuclear radiation detector is compact and lightweight and is primarily used to monitor X, and Y rays. 2High Sensitivity: This nuclear radiation detector is characterised by high sensitivity and accurate measurement. A powerful microprocessor has been selected and equipped with a TFT 2.0 colour screen, making operation easy and humane, with a strong resistance to interference. 3Audible and Visual Alarm: The nuclear radiation detector uses any combination of audible and visual alarms, and the broad alarm value can be set arbitrarily, when the alarm threshold is reached, an alarm will be issued to remind staff of safety in time. 4Wide Application: The nuclear radiation detector is widely used in home radiation, irradiation processing enterprises, health epidemic prevention, radioactive treatment, nuclear laboratory, nuclear power station, import and export commodity inspection, building materials, petrochemical industry, geological census, scrap iron and steel, industrial non destructive detection, etc. There are ionising radiation environment, personal received radiation dose supervision and protection occasion. 5Rechargeable: This nuclear radiation detector comes with a rechargeable battery that can be charged using a USB cable or an adapter. This feature makes it convenient for users as they can use the device for extended periods without worrying about battery life.Item Type: Nuclear Radiation DetectorMaterial: ABSBattery: Lithium battery 3.7V 2000mAh (included)Basic Parameters:Sensor: ForGM counting tubeMeasurement Range: 0.05uSv-50mSvMeasurement Accuracy: -17% to +25% based on 137CsYOperating Environment: Temperature -20C to 50C, Humidity <95% RH no condensationEndurance: 20 days (continuous measurement, no particle sound on)Charging Time: 3-4HourCharging Interface: TYPE C interface (green light always on when charging, full off)Alarm Response Time: <10sTypical Power Consumption: 13mw (no particle sound, rest screen state)Alarm Threshold Deviation: -17% to +25% 12 x 7 x 312 .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 Instruction Manual1 x Storage Bag
