ELECTROMAGNETIC RADIATION DETECTOR: Simple operation, convenient to carry, can quickly measure the intensity of electromagnetic radiation around the equipment. The test frequency band is wide and can be divided into high frequency measurement and low frequency measurement. Accurate testing, the lowest frequency for measuring electromagnetic radiation can be up to 5 Hz<br> FOUL FIT: Health assistants for pregnant women, avoid radiation for the fetus; teenagers and children grow up healthy, scientifically avoid radiation; employees are more dangerous, avoid radiation in the long term; parents are old and have low resistance, and electromagnetic radiation should be kept away<br> LOW FREQUENCY ELECTROMAGNETIC RADIATION: All sources of electromagnetic radiation, such as computers, televisions, copiers, fax machines, air conditioners, refrigerators, stereos, washing machines, power supplies, etc., within the scope of the instrument's test specifications<br> HIGH FREQUENCY ELECTROMAGNETIC RADIATION: Wireless routers, mobile phones, mobile phone signal towers, television signal towers, broadcast signal towers, etc. All sources of electromagnetic radiation in the instrument test the technical indicators<br> ENVIRONMENTAL ELECTROMAGNETIC RADIATION: All sources of electromagnetic radiation in the technical indicators of the instrument test in the room, office, computer room, control room, cables, high voltage lines, monitors, transmitters, etc
