RadMan is worn on the body and emits a loud warning signal when 50% of the maximum permitted flux density is exceeded. An earphone can be attached so the signal can be heard even in very noisy environments. Four LEDs indicate the electromagnetic radiation flux density in stages of 12.5 %, 25 %, 50 % and 100 %.
 
The RadMan XT version is equipped with a data logger.
 
RadMan and RadMan XT are available for the following human safety standards:
  • ICNIRP 1998, Occupational
  • ICNIRP 1998, General Public (E field only, with data logger)
  • BGV B11 2001, Exposure range 1
  • Canada Safety Code 6 99 EHD-237, RF Workers
  • U.S. FCC 96-326, Occupational / Controlled
  • Japan RCR-38, Controlled

 

  • Wide frequency monitoring from 1 MHz to 40 GHz
  • Loud warning buzzer with earphone for noisy environments
  • Shaped frequency response matched to national and international standards
  • Simultaneous E field and H field monitoring for near field use
  • Detachable absorber cap to provide isotropic response for monitoring signals apart from the body (e.g. for leak detection)
  • Calibration every 3 years recommended
  • Data logger for permanent recording (RadMan XT)
