Features:The meter can test electric field radiation and magnetic field emission to up to be the optimal test result.It use to test and learn electromagnetic radiation situation.Fit for both indoor and outdoor using. It is equipped with a built-in electromagnetic radiation sensor, which can display the radiation value on the LCD digital display after processing by control micro-chip.One instrument with two uses, it can test the electric field and the magnetic field radiation at the same time.Sound-light alarm, when the test result exceeds the safe value, the instrument will alarm automatically.Description:Data locking, one-key lock of the radiation value.LCD display of the values for easier reading.Radiation assessment, remind you whether the radiation value is safe or not.Fashionable design, easy on-hand operation, it& 39;s easy to carry and make field measurement.Specifications:Material: PlasticUnit: V/m (Electric Field); T(Magnetic Field)Accuracy: Electric: 1V/m; Magnetic: 0.01TRange: Electric: 1-1999V/m; Magnetic: 0.01-19.99TAlarm Threshold: Electric: 40V/m; Magnetic: 0.4TDisplay: 3-1/2 LCD DisplayTest Bandwidth: 5Hz-3500MHzSampling Time: Approx. 0.4 SecondsTest Mode: Bimodule Synchronous TestOver Range Indication: LCD Displays ""1""Operating Temperature: 0C-50COperating Humidity: Relative Humidity <80%Power Supply: 1 * 6F22 9V Battery (NOT included)Color: Black&OrangeSize: approx. 125 x 62 x 30mmPackage includes:1 x Electromagnetic Radiation Detector
