Application Notes

Measurement is the first step of any shielding project: which source, from which direction, and how strong? Our portfolio includes professional and semi-professional instruments made in Canada (Safe and Sound / Safe Living Technologies), Germany (Gigahertz Solutions) and France (EPE Conseil — Cemprotec). Unsure which instrument to choose? Ask us and we will help you find the right model for your needs.

Application Areas

  • Locating sources and mapping field strength at home and in the office
  • Assessing flats and plots before moving or buying
  • Verifying success after a shielding installation
  • Telling apart base-station, Wi-Fi and DECT sources
  • Monitoring magnetic fields from transformers and power lines

Installation and Application

  • For high-frequency measurements, the meter is held at chest height and moved around, sweeping sources with the antenna; window areas, the head of the bed and your desk chair come first.
  • Peak mode should be preferred over average mode to capture momentary pulsed signals (Wi-Fi, DECT).
  • For magnetic-field measurements, the meter is read on three axes or with a 3D sensor, at different distances around the source.
  • Values are noted down and compared with the SBM-2015 guideline ranges; after shielding, control measurements are taken from the same spots.

Care and Service Life

The meters contain sensitive electronics: protect them from impact and moisture, and remove the batteries for long storage. Do not press on antenna and sensor surfaces; follow the manufacturer's intervals for calibration needs.

Frequently Asked Questions

Which meter is right for me?

For quick checks only, the Safe and Sound Classic 3 class; for reading and comparing values, the Pro 2 or the Gigahertz HF35C; for wiring/magnetic fields, the ME series or the EM3; for 5G mmWave, the Pro mmWave. Write to us with your intended use and we will choose together.

What does µW/m² mean, and what counts as high?

It is the power density per square metre. Building biology (SBM-2015) treats below 0.1 µW/m² as the target for sleeping areas, the 10-1,000 range as serious and above 1,000 as extreme; official limits are far higher. The two are different approaches.

Can phone apps measure this?

No — a phone's hardware is not designed for field-strength measurement, and the results are misleading. A real, calibrated RF meter is needed.

Can I do the measurement myself?

Yes, these meters are designed for home users, and we deliver them with guidance in Turkish. In complex cases (transformers, multi-source situations) a turn-key project survey gives more reliable results.

Delivery and Warranty

Products are delivered in the original YSHIELD packaging, with the manufacturer's warranty, by insured shipping throughout Türkiye. Products sold by the metre are cut to the length you order; for project-based orders the delivery schedule is settled at the survey.

According to the manufacturer YSHIELD, its products are used in more than 150 countries by corporate customers including brands such as Adidas, Amazon, Apple, Airbus, ASML, Google, IBM, Mercedes-Benz, Microsoft, Nike and Siemens.
