EMF Testing Equipment

The instruments we use for remote consultations. Each meter measures something different — and you do not need to buy all of them. After you register, we select the specific meters that match your concerns and show them in your dashboard.

Commonly Recommended

TriField TF2

The most versatile single instrument for a first-time tester. One handheld meter that measures all three field types in one pass.

What it measures: Magnetic fields (0.195–100,000 mG), electric fields (0.195–100,000 mV/m), and RF/microwave (0.195–100,000 mV/m peak). Battery operated, no calibration required.
Best for: Whole-home baseline sweep, bedrooms, living spaces, workstations, Wi-Fi and wireless devices, smart meters, transformers and panel areas.
Limitations: The RF channel is a relative peak indicator, not a calibrated power density. For precise RF work, pair with a dedicated RF meter.

Safe and Sound Pro II

A dedicated RF (microwave) meter for measuring wireless sources with high sensitivity.

What it measures: RF energy 100 kHz–6 GHz, displays mW/cm² with peak hold; covers Wi-Fi, Bluetooth, cell signals, smart meters, and other transmitters.
Best for: Wi-Fi and wireless devices, cellular tower signals, smart meters, baby monitors, and any RF source identification.
Limitations: Measures RF only — it will not show magnetic or electric fields from wiring and appliances.

Optional Alternative

GQ EMF-390

A budget-friendly multi-field meter that covers magnetic, electric, and RF in one device.

What it measures: Magnetic (1–65,000 mG), electric (1–65,000 mV/m), RF (1–65,000 mV/m); multiple ranges per channel.
Best for: General whole-home assessment, bedrooms, appliances, wiring, and a first look at RF sources.
Limitations: Lower precision than dedicated instruments; the RF channel is a relative indicator rather than calibrated power density.

Optional Alternative

LATNEX AF-3500

A sensitive, calibrated RF meter for detailed wireless-source measurement.

What it measures: RF 30 MHz–6 GHz with calibrated mW/cm² output and peak hold; good for distinguishing signal strength from different transmitters.
Best for: Detailed RF mapping: routers, mesh nodes, cell signals, smart meters, and any wireless source you want to quantify precisely.
Limitations: RF only. If your concern is wiring, appliances, or transformers, you also need a magnetic/electric field meter.

Optional Alternative

HF-35C

A handheld multi-range meter for electric and magnetic fields with a wide dynamic range.

What it measures: Magnetic fields and electric fields across multiple ranges, suitable for both small appliance-level and whole-room measurements.
Best for: Bedrooms, office workstations, electrical wiring near occupied areas, appliances, transformers, and electrical distribution equipment.
Limitations: Does not measure RF or dirty electricity; pair with an RF meter and/or microsurge meter for full coverage.

Stetzerizer Microsurge Meter

The standard instrument for measuring dirty electricity (high-frequency voltage noise on your wiring).

What it measures: Measures microsurge / dirty electricity at wall outlets in GS units on a 0–100 scale.
Best for: Outlet-based measurements in bedrooms, offices, kitchens, and near power electronics, inverters, and LED drivers.
Limitations: Outlet-only measurement — it reads the wiring at the plug, not fields in the air. Different outlets can read differently; measure the outlets you actually use.

Choosing Without Guesswork

Customers sometimes feel pressured to buy every meter on a list. That is not how this works. Your dashboard shows only the instruments we recommend for your specific concerns, with a plain-English explanation of why each one.

Typical combinations: one multi-field meter for a general assessment; a multi-field meter plus a dedicated RF meter for wireless concerns; or a multi-field meter plus a microsurge meter when dirty electricity is in play.

Already own a meter? Mark it as owned and we will confirm whether it covers what you need — most customers end up buying less than they expected.
