Safe EMF Headset and Anti Radiation Headphones, Protection Earbuds, Earphones with Air Tube Eliminating Electromagnetic Fields
The stereo acoustic air-tube EMF radiation free headset avoids the use of electrical wires in the ear area. Therefore EMF is not produced by the air-tube and in addition the air tube is not served as antenna because it is not an electrical wire or a conductive material. In addition, the quality of sound is very high because of less interference in the audio signal. The headphones come with changeable earbuds for maximum comfort in S, M, and L. They sit securely and comfortably in the ear shape, even during vigorous exercise. Speakers Sensitivity 110±3Db SPL/3Mw/5cm at 1KHz Range of frequency 20 HZ—-20KHz Resistance 16Ohm ± 15% Rated Power 3mW Capacity 5mW Lead wire length 75cm – 100cm

Electro-Smog Indicator ESI 23 Detector for Low & High Frequency Electromagnetic Fields from 50 MHz to 6 GHz
Elementary analyzer for laymen use, to provide a quick overview of the load situation. Concrete measured values wont be displayed, the measurements are indicated with LEDs in ample colors corresponding to the standard of building biology.
ESI 23: The cheapest device of the series for HF+LF. The 3 types of fields (electric fields, magnetic fields, electromagnetic fields) are indicated with each 5 LEDs.
RF Explorer Spectrum Analyzer 4G Combo PLUS - Slim (0.05 – 960MHz) (2.4– 4GHz)
RF Explorer 4G COMBO+ is a powerful Spectrum Analyzer, covering the full range starting at 50KHz up to 4GHz with no gaps or limitations. A future firmware license feature will allow it to expand the range up to 5.1GHz.
When compared to the standard 3G Combo model, the new SLIM design offers an outstanding robust enclosure with a strong metallic body and shiny varnished paint, additional frequency coverage, and power sensitivity, a more convenient USB connector on the side and larger internal battery capacity.
What is an RF Explorer Spectrum Analyzer?
An RF Explorer Spectrum Analyzer is a special device designed to detect very sensitive signal radiation and identify signal interference, tune antenna setups, detect signal leakage and find hidden bugs, among many other applications.
The combination of small size, great sensitivity, and robust design makes it the ideal instrument to carry on for indoor and outdoor measurements.
When connected to a computer, it can be controlled by free software available for download with stunning high-resolution graphics, data storage, and reply features.
