Portable Electromagnetic Field Radiation Detector LCD Backlight Meter Description: Large LCD Display Screen: Adopt large LCD display screen, the value can be clearly displayed on the screen and easier do read and provide better experience. Application: It can simultaneously detect electric and magnetic field, allows you to get two important values in the test. Dual alarm function: double sound and light alarm function, automatically alarm when the test value exceeds . Data retention function: You can briefly press the "Power / HOLD" button and the reading will be blocked, and [HOLD] will appear on the screen, press again to resume the normal measurement, and [HOLD] will not appear. Portable size and easy do carry: you can easily use it with your hand and carry it with you anywhere. Assessment function: which can indicate whether the current value is level, the three-color light indicates the current field states: , , inversion and if the electric field data exceeds Specification: Material: ABS Unit: Electric field: V/m Magnetic field: uT/ Precision: Electric field: 1V/m Magnetic field: 0,01uT/0,1mG ranges: Electric field: 1-1999V/m Magnetic field: 0.01-99.99uT/0.1-999.9mG Emergency threshold: Electric field: 40V/m Magnetic field: 0.4uT/4mG Measurement: 5 Hz-3500 MHz Sampling time: about 0,4 s Overload signalling: maximum value of measuring ranges on the LCD display Operating temperature: 0-50C Operating humidity: relative humidity below 80% Operating Voltage: 4,5 V Size Chart: 130x64x27,5mm/5,12x2,52x1,08 inch The package includes: 1 piece Electromagnetic Tester
