Electromagnetic field radiation detector Emf meter rechargeable handheld portable counting radiation dosimeter computer One machine with two functions, detecting electric field and magnetic field radiation at the same time; sound and light alarm, automatic alarm when exceeding the safe value; data lock, one-key lock radiation value; LCD graphic display radiation value trend; radiation evaluation, closely reminding whether the current radiation value is safe; Appearance Stylish and easy to operate with one hand, it's easy to move or measure in the field. feature The instrument can test electric field radiation and magnetic field emission to achieve the best test results. It is used to test and learn the electromagnetic radiation situation indoors and outdoors. It is equipped with a built-in electromagnetic radiation sensor, which can display the radiation value on the LCD digital display after processing through the control microchip. One instrument does two things, it can test both electric and magnetic field radiation. Sound and light alarm, when the test result exceeds the safe value, the instrument will automatically alarm. Data lock, radiation value one-click lock. LCD display value, easy to read. Radiation assessment to remind you whether the radiation level is safe. save data low battery reminder Automatic shut-down Stylish design, easy operation, easy to carry and on-site measurement.
