18-Step Working-Window

The MITO METER 2.0 [EURO] uses an 18-step colour LED Working Window to display EMF levels — with no confusing numbers to interpret.

The first nine LEDs are aligned with EUROPAEM, TCO, the BioInitiative Report, and Building Biology guidelines, so the colours reflect real-world biological relevance, not just signal strength.

From left to right, 4 green → 3 yellow → 2 red LEDs illuminate across RF, Magnetic, and Electric Field modes, making it easy to see whether a space is clean (no LEDs), borderline, or heavily polluted — and to quickly locate sources or confirm whether shielding or grounding is working.

RF Mode (Radio Frequency/5G)

Biological guidelines suggest outdoor background RF should ideally remain below 50 µW/m², with 100 µW/m² considered the upper public exposure limit.

The Mito’s main RF Working Window spans 0.5 to 50 µW/m², displayed across 4 green → 3 yellow → 2 red LEDs. As RF levels rise beyond this range — that we typically work within — the green LEDs drop out first, followed by the yellow LEDs as exposure moves into extreme-levels.

At the upper end — deep into the red extreme zone — only the red LEDs remain, with the audible max alarm activating at 100,000 µW/m² as the display maxies out. (The alarms can be switched off.)

For living and sleeping areas, recommended levels are far lower — below 1 µW/m², and below 0.1 µW/m² for bedrooms. In clean environments, no LEDs will light, which is ideal for children, the health-conscious, and EMF-sensitive individuals.

The RF-Xs Sound Signature Mode can also be used to detect very low-level signals and help identify active RF sources.

LFM Mode (Magnetic Fields)

The main Working Window runs from 10 to 100 nT (0.1–1 mG) because long-term exposure to background dynamic magnetic fields from the power grid should ideally remain below ~20 nT (0.2 mG) at night and 100 nT (1 mG) during the day, as widely referenced among bio-friendly guidelines.

Above 100 nT (1 mG), the green and yellow LEDs drop out one by one, leaving only red LEDs in extreme conditions, with the maximum alarm sounding at 2,000 nT as the display finally maxes out.  (The alarms can be switched off.)

Homes in heavily populated areas often rise to 100–200 nT (1–2 mG) at different times of the day and night, which is why LFM-X Mode records these magnetic fields over 12 hours to display daily or nightly averages.

LFE Mode (Electric Fields)

Most people sleep in around 1 V/m of 50/60 Hz AC (alternating current) electricity. Guidelines suggest aiming for < 0.3–1 V/m at night and < 10 V/m in working areas such as at your office desk.

The Mito’s Working Window runs from 1 to 30 V/m, as many people using laptops — especially when plugged in or connected via Ethernet — experience electric fields up to 30 V/m due to non-grounded setups. (Or incorrect grounding.)

Above 30 V/m, as you approach extreme conditions, the green and yellow LEDs progressively drop out, leaving only red LEDs, with the maximum alarm sounding at 1,000 V/m.  (The alarms can be switched off.)

For sleeping areas, the goal is no illuminated LEDs within 1–2 meters of the bed. (measured while holding the meter—body potential reading).

Accuracy Notes

Unlike the Mito Meter, most 3-in-1 EMF meters do not measure much below 100 nT (1 mG), even when their specifications claim they do. Many 3-in-1 meters also cannot detect below 10–20 V/m for electric fields.

Gigahertz Solutions meters aside, all RF meters — including the Mito Meter and leading professionally certified and calibrated brands such as the Safe & Sound Pro II — vary by about ±6 dB. (Gigahertz Solutions ±3 dB — half below variances.)

±6 dB means:

• 1 µW/m² may read 0.25 to 4 µW/m²

• 1,000 µW/m² may read 250 to 4,000 µW/m²
