Features: Portable Size: This handheld electromagnetic radiation detector is portable in size and easy to carry, so you can put it in your bag and take it with you and easily grip it for use. Shockproof Housing: The housing is made of plastics material that feels comfortable in the hand, wear resistant and impact resistant, can provide long service time.High Accuracy Sensor: Built-in magnetic field electric field sensor, can measure the electric field strength, radiation power, magnetic field strength, static magnetic field polarity. Color Display: TFT2.0 color screen with backlight, clear definition with and colorful font design, real-time display test data, it can easily cope with dim and bright environments to give you a more comfortable experience.Data Lock Function: Equipped with data lock function, one click to lock the radiation value, easy to record the relevant data. Multifunctional Design: Support real-time measurement, electric field waveform, magnetic field waveform, alarm setting, unit setting, power saving setting, language setting, limit value standard, etc. Multiple Alarms: When the detected environmental radiation exceeds the alarm value, the instrument will be prompted sound alarm and the display will alarm at the same time.Graphical Radiation Level Grading Function: Equipped with the current radiation level grading function, different colors correspond to different current radiation levels, allowing for a more accurate and graphical understanding of the current environment.USB Rechargeable Battery: Built-in higher performance lithium battery, USB rechargeable design, more convenient to use. Wide Applications: This radiation tester can be widely used in the home, office, outdoors, industrial sites, radiological laboratories, and the surrounding environment; It is also suitable for televisions, refrigerators,and high-voltage line radiation detection monitors.Handheld electromagnetic detector, mainly used to detect the electric field strength, radiation power and magnetic field strength. Equipped with TFT 2.0 color screen, graphical operation menu, display intuitive and easy to use. With electric field and magnetic field waveform display mode. Average value maximum value button for quick switching, HOLD button for data holding. There are two alarm combinations of sound and flash and the alarm threshold can be set arbitrarily. Easy to operate, the test starts automatically when the power is turned on, and the display can continue to measure after the automatic sleep, and the automatic shutdown mode can also be set. Chinese and English bilingual menu design, the user can freely switch.Specifications:Material: plasticsBattery: 1 x built-in 750mAh battery (included)Display: TFT2.0 displayFrequency response: 50MHz-3.5GHzElectric field strength: 0.1-200V/mRadiation power: 0.2-1000mW/mMagnetic field strength: 0.1-1200GsMeasurement direction: uniaxialMeasurement unit: Magnetic field: mT and GsElectric field: V/mRadiation power unit: (W/cm and mW/m)Protecting level: IP3XItem size: 118 x 51 x 20mm / 4.65 x 2.01 x 0.79inColor: WhiteMaterial: plasticPackage Contents:1 x Radiation DetectorOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
