HF 58B-r

A professional grade model with everything a Building Biologist might need.  Especially useful the ability to discern pulsed and analog HF radiation. 

The radar module sets standards in this category of devices. Its functions and features are tailored to the needs and practical experiences of the building biology. Due to its comparably low price, it is often also used for scientific and industrial purposes, especially in the cell phone and wireless sector.

Characteristics

  • Audio Analyses for the identification of pulsed radiation sources (mobile radio (GSM, UMTS/G3), cordless telephones (DECT), WLAN (Bluetooth), air-traffic control-radar) by means of an acoustic signal proportional to the modulation frequency
  • Display of peak value as well as average value (switchable)
  • Sensitivity increased by a factor of 10 (from a minimum display resolution of 0.1µW/m² to a maximum of 1999 µW/m²)
  • A quantitative differentiation between pulsed and un-pulsed radiation - a unique feature within the broadband measuring technology (based on our patent DE10317805)
  • A switch for 2 MHz video bandwidth, allowing especially precise measurements, also of ultra short RADAR signals within the frequency range subject to measurement with a minimum pulse length of up to 0.5 micro seconds, as well as of UMTS-FDD/3G
  • Especially high speed of response in the operational mode "peak hold" (patented)
  • A NiMH battery, a battery charger and a power supply unit inclusive.
