HFW35C RF Meter Video

Specialized, Intermediate level RF Analyzer for Higher RF Frequencies


New wireless technologies such as Bluetooth, WLAN, WiMAX and cordless telephones operate in the higher frequency ranges of 2.4 GHz – 6 GHz. The HFW35C has been designed to detect and measure the RF emissions generated within this range.


·       The compact and sturdy LogarithmicPeriodic Antenna has been engineered to capture the shorter in length, radio frequency waves emitted by wireless devices employing high frequency radio waves

·       Readings increase when the antenna is pointed in the direction of or moved closer to offending sources

·       Built in filters actively weed out frequencies outside of the 2.4 GHz– 6 GHz range. This allows for confident measurement of sources within the desired frequency range

·       Detects RF radiation generated by WLAN/WiFi (2.4 – 5.0 GHz); 5.8 GHz Cordless Phones, and more…




Professional Level Features Offered at a Unique Price to Performance Ratio:


·        The audio tone replicates the patterns and intensity of measured RF emissions

·        Pulsed Digital Signal Setting or Analogue Signal Setting allows for in depth signal identification and source identification as well as facilitating risk assessment (studies show that digital signals have the greatest biological impact)

·        A Fine range option provides added value when needing accurate assessment of weaker signals.  (Coarse:  0 – 1999 µW/m² and Fine: 0 – 199.9 µW/m² Range Options)

·        Peak Settings and Average Settings:  While measurements taken on the Average Value setting provide a general impression of RF levels at a test site, the Peak Value setting reveals the highest levels of RF being emitted. The Peak Value is regarded as the measurement critical to assessing potential biological effects
