Our top of the range HF instrument.

Frequency from 700 MHz up to 2.7 GHz

Focus on professional HF measurements and rehabilitations:

  • Self-compensating, optimized log.-per. antenna from 700 MHz to 3.3 GHz with higher accuracy, especially at the critical lower and upper end of the frequency range. Allows a perfect display of the 700 MHz 5G band, which is particularly important for this range, as well as of all other cell phone services such as GSM (2G), UMTS/CDMA (3G), LTE (4G), 5G (wide area bands), wireless phones, smart meters, the lower wireless LAN / Wi-Fi band, Bluetooth. (The frequency range of the base units starts already at 27 MHz - therefore it is suitable for the connection of the UBB antenna).
  • High sensitivity: display resolution 0.01 µW/m². An important factor especially for EHS patients (electrohypersensitives). The external preamplifier HV10 allows a further increase of the sensitivity!
  • Maximum measured value 19.99 mW/m² (= 19,990 µW/m²), additionally increased by a factor of 100 if used with the attenuator DG 20_G10.
  • Measurements are much simplified by the "peak hold" function. Particularly fast response speed due to a patented circuit.
  • Calibrated AC measurement output for the demodulated signal, scalable DC output, for instance for a connection to our NFAs for long-term recordings.
  • Quantitative differentiation of pulsed <> unpulsed radiation according to the building biology recommendations.
  • NiMH battery pack, charge control and power supply unit help avoid unnecessary battery wear.

Delivered in a plastic case K2 with shaped foam filler for a safe transportation of all components.

Manual

Technical Data

Frequency range:

A frequency range of down to 27 MHz within the basic device - suitable for the connection of an optionally available antenna (the scope of delivery includes a compensated antenna for 700 MHz up to 2.7 or 3.3 GHz)

Measurement range:

Power flux density: 0.01 - 19,990 µW/m²

Precision:

Basic accuracy (CW) including linearity tolerance: +/- 3 dB

Zero offset and rollover +/- 5 digits

Sensor:

Optimised logarithmic periodic antenna with frequeny compensation directly on the antenna. Less ripple, better directionality, improved shielding vs. ground, continuous LED-monitoring of quality of connections

Audio analysis:

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.

Signal rating:

Display of peak value, peak hold as well as average value (switchable)

Quantitative differentiation between pulsed and un-pulsed radiation (patented control)

Signal output ports:

A calibrated extra AC-measurement output for the demodulated signal, and a DC-output

Power supply:

Rechargeable highpower 9.6 Volt NiMH battery pack inside the meter, average operation time: 7 - 8 hours

Low-Batt. indication

Auto-power-off (can be deactivated for long-term measurements)

AC-adaptor for charging and long-term-operation included
