High Frequency Meters

High Frequency Meters

High frequency electromagnetic fields (EMF) are commonly used in cellular radio, broadcasting, satellite communication, radar systems, industrial processes such as melting, semiconductor production and microwave systems. Air-Met Scientific is the exclusive Australian distributor for the Narda Safety Test Solutions EMF product range and offer a complete range of handheld monitoring devices for the monitoring of high frequency radiation in the workplace.

Health effects of high frequency fields

Electromagnetic fields have been known to have certain biological effects which may be detrimental to human health. Health effects from over-exposure to high frequency electromagnetic fields include burns and tissue damage. The effects of electromagnetic fields and the extent of the health effects is dependent on a few factors including:

  • the frequency 
  • the field strength 
  • the field type (E or H field) 
  • the duration of the exposure
  • the extent of the exposure (how much of the body has been exposed to radiation)
  • the signal shape

National and international bodies have specified limit values for electromagnetic radiation specified to protect people from harmful exposure. Air-Met’s range of high frequency meters are designed to ensure occupational radiation exposure are within safe limits (occupational or general public limits) and comply to the relevant governing regulations. Our product range includes:

SRM-3006 Field Strength Analyser: The SRM-3006 is a compact handheld EMF monitor that consists of a base unit and measuring antennas for non-directional detection of high frequency electromagnetic fields and their sources in the range of 9 kHz to 6 GHz. Ideal for safety analysis and environmental measurements of high frequency EMFs.

NBM-500 Broadband Field Meter Series:Narda’s NBM 500 Series of Broadband Field Meters have been designed to detect high frequency electric and magnetic fields with non-ionising radiation frequencies of up to 300 GHz for personal safety. Renowned for their precise, reproducible, and calibrated measurements so that they can be traced back to standards, the NBM 500 Series of Broadband Meters consists of two models; the NBM 520 and the NBM 550, and are ideal for measurements in the laboratory as well as for the detection of leaks in high frequency lines or devices.

NIM-511 and NIM-513: Featuring two sets of sensors that are capable of separately measuring each field, the NIM-511 and NIM-513 are complete measurement systems designed to simultaneously measure electric and magnetic fields up to 100 MHz. Low cost, compact and easy to use, these meters are ideal for radiation monitoring in most industrial environments and are suitable for radiation monitoring of RF heat sealers, vinyl welders, semiconductor process equipment, plasma generation systems, dielectric dryers and heaters and more.
