- Used to measure electromagnetic radiation in living and work environments such as offices, computer rooms, power distribution rooms, and transmission towers. - Sound and light alert: the tester automatically alarms when the measurement exceeds the safe limit. - Display features: shows the maximum value, provides a HOLD function to freeze the current reading on the LED screen, and a long-press on the power button to turn off the backlight to save power. - Built-in sensors and display: integrated electromagnetic radiation sensors feed data to the LED display after chip processing, allowing you to interpret results and take preventive actions. - Practical uses: monitor desk areas at the office to assess exposure from devices, check EM levels in data centers or server rooms around racks, and assess exposure during field work near transmitters or towers. - Clear, reliable readings support informed decisions about shielding, distancing, or other controls based on tester results.
