ENV RD-100 Advanced Home EMF Meter – Designed for EHS, by EHS & EMF Specialists

The ENV RD-100 is our highly recommended all-in-one home EMF meter (introduced in 2025). Developed in Israel through a close collaboration with us, it is specifically designed to meet the rigorous demands of electro-hypersensitive (EHS) individuals and health-conscious users seeking an accurate, fast, and easy-to-use EMF Meter.

Why Choose the ENV RD-100?

  • 3-in-1 Meter (ALL-IN-ONE): Simultaneously or individually measures Radiofrequency (RF) radiation, Low-Frequency Magnetic Fields (LFM), and Low-Frequency Electric Fields (LFE).

  • Ultra-Fast Sampling Rate: An incredible 60,000 samples per second! This is the most crucial metric for capturing the brief, rapid, and aggressive RF pulses of modern wireless technology (including 5G, Smart phone, smart devices, Smart meters and Military Technologies).

  • Simplicity Meets Professional Depth: Features an intuitive 4-LED indicator system for beginners (calibrated to strict health safety thresholds according of our and others understanding of the possible health risk, rather than lax government standards), alongside a comprehensive graphical LCD screen for advanced users.

  • Advanced Audio Feedback & RF Modulation: "Hear" the invisible. The built-in speaker and modulation display allow you to identify specific signal sources (such as Wi-Fi, Bluetooth, or cell towers) by their unique acoustic signatures.

Exclusive Value from "For EHS By EHS": When you purchase from us, you don't just get a device—you get the full package:

  • Each meter is individually tested and calibrated against reference meters by Amir before shipping.

  • Includes an easy-to-follow User Manual with recommended safety threshold tables.

  • Step-by-step guidance, video tutorials, and dedicated initial email support to help you start measuring with confidence.

2-Year Limited Warranty.

]]> ENV RD-100: Co-Developed and Tested for Ultimate Home EMF Assessment

The ENV RD-100 was born out of more than 20 years of practical experience of being an EHS person,  supporting EHS individuals and raising EMF awareness. We realized that users need a meter that is extremely simple to operate straight out of the box, yet powerful enough to deliver professional-grade diagnostics when locating radiation sources, and mitigating EMF exposure.

Dual-Mode Functionality: Tailored for Every Level of Expertise

  1. Beginner Mode (Instant Awareness): The radiation level is instantly represented by 4 clear LEDs (Green, Yellow, and two Reds). The threshold levels for these LEDs are configured based on our and others understanding of the possible health risk, rather than lax government standards, giving you instant peace of mind without needing to interpret complex scientific formulas.

  2. Advanced Mode (Scientific Precision): A large, detailed LCD screen displays real-time data:

    • Peak values (re-calculated every half-second) and maximum peak since power-on.

    • Average values (30 seconds average).

    • Duty Cycle measurements (the percentage of active transmission time) in RF mode.

    • Signal frequency in low-frequency magnetic (LFM) and electric (LFE) modes.

    • A 30-second history graph showing real-time fluctuations.

Key Features and Practical Benefits:

  • Joint Mode (One-Screen Scan): View all three EMF types of EMF (RF, LFM, LFE) simultaneously on a single screen. This allows you to quickly scan a room/car/apartment/office and immediately spot which type of field is elevated.

  • RF Modulation Display: View on the meter’s screen (and hear via the speaker) the wave shape of the RF signal over a 100ms or 0.5s window, assisting in identifying the exact nature of the wireless source.

  • Data Logging via PC (Optional): Connect the meter to a PC or Android device using a specialized active USB Serial cable (sold separately) to record and analyze measurements over hours (perfect for overnight bedroom monitoring).

  • Long Battery Life: Runs on 2 standard AA batteries, offering up to 20 hours of continuous operation (when using quality alkaline batteries).

  • Built to Last: Comes with a custom protective carrying case for safe storage and travel.

  • Made in Israel: Proudly developed, manufactured, and shipped from Israel.

Technical Specifications:

  • Measurement Types: Radio Frequency Radiation(RF), LF Magnetic Fields(LFM), LF Electric Fields(LFE).

  • Max Sampling Rate: 60,000 samples per second.

  • Display: Graphical LCD + 4-LED quick indicator.

  • Audio: Internal speaker for RF modulation feedback (RF sound signature).

  • Power: 2x AA batteries.

  • Warranty: 2-year limited warranty.

]]> The S190 is a China-made RF Blocking fabric.  The S190 fabric has a composition of cotton, polyester, and Stainless Steel metal fibers.
It is a DOUBLE LAYER WOVEN  190 g fabric. One side/layer (the Gray side) includes stainless steel fibers. The other side/layer has no steel in it.

About the S190 RF EMF/EMR Blocking Fabric

RF Blocking effect – Fabric’s RF blocking effect = 27-37dB according to the manufacturer’s datasheet. (Frequencies of 1GHz to 10GHz).
The fabric was tested by us and showed a good RF-blocking effect.
Our tests showed that the RF blocking effect was at least ~99%/-20dB (using CORNET ED88T in front of a DECT Phone 1.8GHz in a special testing cage 10/2018.
In most of the tests, we have seen even better outcomes.

The fabric does not block ELF magnetic fields from electric cabinets/equipment and power lines).
The fabric was tested again and again and showed good results even after more than 15 laundry cycles in a washing machine at 40 degrees Celsius, with soap.
  • The Fabric is durable and its ability to block RF is not reduced over laundry cycles.
  • Composition:  20% cotton, 57% polyester, and  23% Stainless steel metal
  • Weight:190 gr/m2
  • Roll Width:145 cm  (57″)
  • Weaving pattern: woven fabric
  • Colors:  One side is Light Gray, and the second side is Gray.
  • Washable 400 degrees Celsius in a washing machine,
    – Use Gel/Liquid/Powder detergents.
    – No bleaching
    – No drying in tumble dryers
    – No chemical dry-cleaning
    – You can expect the fabric to withstand more than 30 cycles of washing, with a minimal reduction in its ability to block RF.
  • Durable
  • Flexible
  • It can be reused many times for different needs.
  • Made in CHINA
