A precision RF meter with extended-range coverage for measuring wireless and microwave signals around the home. The HF35C is a trusted tool among EMF consultants for surveying Wi-Fi, cell, and tower exposure with clear analog and audio readouts. Built for anyone serious about understanding their RF environment.

The HF35C uses a Logarithmic Periodic antenna for directional detection of RF waves — readings increase as the meter is pointed toward an offending source. A Course measurement range (1 — 1999 µW/m²) handles stronger fields, while the Fine range (0.1 — 199.9 µW/m²) offers higher sensitivity for lower-level signals. Audio output produces a Geiger-counter-like tone proportional to field strength to aid in source identification, and Peak vs. Average settings let you capture either the highest momentary spikes or a representative reading at a test site.

  • Frequency range: 800 MHz — 2.5 GHz
  • Measuring range: 1 — 1999 µW/m² (up to 199,900 µW/m² with external DG20 attenuator)
  • Accuracy: +/- 6 dB basic (including linearity tolerance); zero offset and rollover +/- 9 digits
  • Sensor: Logarithmic Periodic antenna
  • Signal rating: Full signal only (Analog plus Digital/pulsed)
  • Power: 9V alkaline manganese battery (included)
  • Battery life: 10-12 hours typical operation
  • Auto power off: after 40 minutes of continuous use
  • Dimensions: 2.75" W x 9" L x 1.25" H
  • Weight: approximately 10 oz
  • HF35C Radio Frequency Meter
  • Logarithmic Periodic Antenna (700 MHz — 2.7 GHz, vertically polarized)
  • 9V alkaline battery
  • User's Guide

The GigaHertz Solutions HF35C offers a unique package of basic RF measurement features at an affordable price.

  • Easy to operate — power on and walk through your living space
  • Identifies peak readings via LCD digital display
  • Directional detection helps locate RF source
  • Audio identification — tone replicates signal patterns to aid source identification
  • Peak and Average measurement settings for full assessment of RF emissions

Detects RF radiation from cellular and cordless phones (digital or DECT), microwave ovens, Wi-Fi routers, WLAN, baby monitors, Bluetooth, video games, smart meters, and cell phone towers operating between 700 MHz and 2.7 GHz (GSM, UMTS, 2G, 3G, 4G). Detects both analog and pulsed digital signals.

2-year manufacturer warranty. Every HF35C is individually calibrated to a traceable standard during manufacturing using high-end calibrated measurement instruments.

Full product details

The GigaHertz Solutions HF35C offers a unique package of basic measurement features at a very affordable price.

Product Features:

  • Easy to operate, power the unit on and then walk your meter through your indoor living space. The LCD digital display will allow you to identify peak readings
  • Equipped with a sturdy Logarithmic Periodic antenna designed for directional detection of RF waves. Readings increase when the meter gets closer to or points in the direction of offending sources.
  • A Course measurement range and Fine measurement range provide added value when needing to assess RF emissions
  • Course range covers stronger readings of 1 - 1999 µW/m²
  • Fine measurement range of 0.1 - 199.9 µW/m² offers higher sensitivity and allows for accurate detection of lower level signals
  • Detects RF radiation generated by cellular and cordless phones (Digital or DECT); microwave ovens; wireless communication devices such as internet routers, WLAN, Wi-Fi, baby monitors, Bluetooth, video games, smart meters and cell phone towers in the operational range of 700 MHz to 2.7 GHz (GSM, UMTS, 2G, 3G, 4G)
  • Detects both analog and pulsed digital signals (1 - 1999 µW/m²)

Extended Range Features:

  • Audio Identification: The meter's audio tone replicates the signal patterns and intensity of measured RF emissions and aids in source identification
  • Peak Settings and Average Settings: While measurements taken on the Average Value setting provide a basic sense 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

Calibration:

During the manufacturing process strict calibration procedures are followed using only high end, calibrated measurement instruments. This guarantees that every HF35C meter made by Gigahertz has been individually calibrated to a traceable standard. Ships via Standard Delivery

Questions

What does it detect?

RF emissions from cell and cordless phones (digital/DECT), microwaves, Wi-Fi/WLAN, Bluetooth, baby monitors, smart meters, and cell towers from 700 MHz to 2.7 GHz.

What is the difference between Peak and Average?

Average provides a basic sense of RF levels at a test site, while Peak reveals the highest momentary levels — considered the critical measurement for assessing potential biological effects.

How long does the battery last?

Approximately 10-12 hours of continuous operation. The meter will auto power off 3 minutes after a battery low signal.

Is it calibrated?

Yes — every HF35C is individually calibrated during manufacturing to a traceable standard.
