Feature:1. Multifunction, it can detect electric and magnetic field radiation at the same time, and carry out radiation evaluation, and intimately remind whether the current radiation value is safe.2. Sound and light alarm, when detecting that the radiation exceeds the safe value, it will automatically alarm to protect your health and safety.3. Data lock, it can easily lock the radiation value with one key, and it is convenient to measure and record the data.4. Highdefinition LCD display, which can display the trend of radiation value through graphics, so that the fluctuation of radiation can be seen more clearly.5. Stylish appearance, it can be easily operated with one hand, convenient for mobile or onsite measurement, and can be used for measurement in various situations.Specification:Item Type: Radiation DetectorModel: ET825Material: ABSPower Supply: 3xAAA 1.5V Battery (Battery Not Included)Application: It is suitable for electromagnetic radiation testing.Monitoring Places: It can detect radiation in homes, offices, outdoors, and industrial places.Testing Items: It can perform radiation testing on mobile phones, computers, TVs, refrigerators, and high-voltage lines.Radiation Protection Products Inspection: it can test the effects of radiation protection clothing, radiation protection films and other protective equipment.Technical ParametersElectric FieldMagnetic FieldUnitV/m(Volt/Meter)T Accuracy1V/m0.01TRange1V/m-1999V/m0.01T-99.99TAlarm Threshold40V/m0.4TReading Display3-1/2 Digit LCD DisplayTest Bandwidth5Hz-3500MHzSampling TimeAbout 0.4 SecondsTest ModeDual Mode Simultaneous TestOverload PromptLCD Display Maximum RangeOperating Temperature0-50Operating HumidityRelative Humidity Below 80%Operating Voltage9V.Package List:1 x Radiation Detector (Battery Not Included)1 x ManualNote:1.
