Color coded radiation level indicators with five LEDs Dark green: 0 to 1.5 milligauss Green: 1.5 to 2.5 milligauss Blue: 2.5 to 10 milligauss Orange: 10 to 20 milligauss Red: 20+ milligauss Keeps you informed about radiation by providing quick, ataglance visual feedback of exposure levels. Application and performance Application: 50/60 Hz frequency monitoring in typical electrical environments. Special function: 5LED indicators represent different radiation values; userfriendly. Function: Offers clear, color coded indication of magnetic field exposure to assist in identifying higher radiation areas. 23 practical use scenarios Home or office near electrical equipment such as outlets, power strips, or computer equipment, to quickly assess exposure levels. Electrical maintenance or installation work to find areas with elevated 50/60 Hz magnetic fields and make adjustments to positioning or shielding. Workshops or labs with machines operating on 50/60 Hz, to monitor exposure during operation and ensure safer working distances. Notes Based on milligauss measurement ranges and color mapping, the device focuses on ease of interpretation and rapid decision making in daily environments.
