RF survey meters are used to measure the electromagnetic field (EMF) strength to analyze the integrity of a signal and establish if the sites around RF radiation emitters are safe. Carrying out RF surveys is essential for businesses surrounding telecommunications, broadcasting, and radar systems. Antennas produce high levels of RF that need to be tested to ensure people are not being exposed and that it is not interfering with neighboring sources.
Two types of survey meters are broadband and selective. Broadband RF field meters are used with both isotropic E-field and H-field probes that are then categorized into flat probes and shaped probes. Shaped probes are designed to comply with industry standards provided by FCC, IEEE, ICNIRP, and Canada SC-6, and other similar standards. These tests provide users with the percentage of the standard achieved for the environment under test. Flat probes are to be used within a particular frequency range. Selective radiation meters use E-field and H-field antennas with single-axis or three-axis measurements for both low and high-frequency testing. Three-axis antennas are the most convenient due to their automatic delivery of isotropic results.
Avalon Test Equipment carries a variety of RF survey meters for rent or purchase so you can Test With Confidence®.
The Narda-STS NBM-550 Logging Broadband Field Meter is the most accurate non-ionizing radiation survey system available. It performs electric and magnetic field measurements from RF to microwave. Both flat response probes and probes shaped to international standards are available.
The Narda Industrial Meter NIM is a complete measuring system with combined E and H field probe for simultaneous measurement of electric and magnetic fields on equipment operating at ISM frequencies. NIM-511, calibrated at the 13.56 MHz ISM frequency, covers a wide frequency range of industrial equipment. The device was specially developed for measurements on industrial equipment e.g. for high frequency welding, glass coating, semiconductor production, RF induction ovens, plasma generators or dielectric heating and drying systems.
Narda-STS SRM-3006 is a second generation, hand-held system for performing narrowband analysis of electromagnetic fields. It has the ability to give results of individual emitters and also generate a total of all emitters.
