Microrad RF Fieldmeter

Users can measure from static/almost static magnetic fields up to 6GHz utilising only two probes while remaining compliant with Directive 2013/35/EU. This solution is the NHT-3D meter plus 33P and 01E probes

These instruments are flexible and easy to use, yet sufficiently powerful to analyse electromagnetic pulse fields with specific application software for remote control and time/frequency analysis.

Key Points

  • Measures RF, electric and magnetic fields
  • Comply with CEMFAW (2016) and ICNIRP
  • Operate manually or programmed (unattended) mode
  • Auto location (GPS) and date/timetagging of every sample
  • Plot locations on Google maps

There are 2 elements to the Field meters:

The Meters:

Laplace supplies the MICRORAD series of meters and probes that fully meet the requirements of the relevant standards, including ICNIRP (International Committee for Non-Ionising Radiation Protection) and CEMFAW [2016] (Control of ElectroMagnetic Fields At Work regulations).

The Microrad range is based on 2 types of meter:

  • The NHT-310 – ideal for RF field evaluations. Frequency coverage up to 40GHz.
  • The NHT-3D for complex field evaluations. Frequency coverage for the complex analysis is up to 400KHz. This includes full assessment of ICNIRP thresholds, public and occupational levels, FFT analysis and time domain analysis (CEI EN 62233), oscilloscope mode. The NHT-3D also covers the field evaluation range up to 40GHz.

Both meters include GPS positioning, data logging, 100dB dynamic range without range changing, temperature sensing, USB and fibre optic communications and PC software.

The Probes:

  • A range of plug-in probes is available to compliment the meters. Each probe covers a specific type of field and frequency range. Selection should be based on the particular requirement. Uniquely, the MicroRad range includes 2 models of combined probe (the type 33N, DC to 20KHz and the 33P DC to 400KHz) which will measure all three fields without the need to change the probe.

These probes are isotropic with highly dynamic response to pulsed signals, prerequisites for today’s needs when measuring electromagnetic fields from digitally modulated sources.
