Quick Verdict
The TriField TF2 is the meter I use for every room audit on this site. It measures all three types of EMF — magnetic, electric, and RF/microwave — in a single device. For a home audit, it’s the only meter you need. Real measurement data from my Palm Beach home is incoming — this review will be updated the moment I complete the full room-by-room walkthrough.

This is for you if…
- You want to audit your home for all three EMF types
- You’re concerned about bedroom RF exposure from WiFi
- You want professional-grade data, not a toy detector
- You’re sleeping poorly and want to rule out environmental factors
- You work or sleep near electrical infrastructure
Not the right fit if…
- You only need dirty electricity measurement (needs a separate filter meter)
- You want ultra-high RF sensitivity above 6 GHz (5G mmWave)
- Budget is under $150 AUD — there are cheaper options, with trade-offs
Why I Use the TF2
Most of what gets sold as an “EMF detector” in the sub-$50 range is a single-axis magnetic field meter dressed up with LEDs and an alarm. It measures one thing, imprecisely, and tells you very little about your actual exposure profile. The TF2 is different in three meaningful ways: it covers all three EMF types in a single calibrated unit, it uses three-axis sensing for magnetic fields (so you don’t have to rotate the meter to find the peak), and its RF measurement range covers the frequencies that actually matter in a modern home — WiFi, 4G/5G, smart meters, and Bluetooth.
I’m a former Navy Clearance Diver. My professional background was built around trusting instrumentation and making decisions based on what the data actually says, not what you assume. That’s the framework I apply to home environment audits. The TF2 is the instrument I trust for this. It’s used by building biologists, industrial hygienists, and environmental consultants. It happens to be accessible to homeowners at a reasonable price point.

The reason I’m documenting this properly rather than just stating general conclusions is direct: this site is built on the premise that measurement matters. Anyone can repeat talking points about EMF exposure. The useful contribution is actual data from an actual Australian home. That data is coming and will be posted here as soon as the audit is complete.
What I Like About the TF2
Three-axis magnetic sensing. Single-axis meters require you to rotate them to find the peak reading — a meaningful source of error and inconvenience during a room audit. The TF2 measures all three axes simultaneously, which means you hold it still and get an accurate peak value. For an amateur auditor this removes a real source of user error.
The frequency-weighted mode. In addition to the standard flat measurement mode, the TF2 has a weighted mode that scales readings to reflect the induced current in the human body across the frequency spectrum. It’s a more biologically relevant measurement and it’s not something you find on cheaper instruments.
Build quality and display. The TF2 feels like a professional instrument. The display is clear in all lighting conditions, the controls are intuitive, and the peak hold function — which captures transient signals that would otherwise be missed — works well. Battery life is rated at 20+ hours on a standard 9V. In practice I haven’t needed to change the battery yet through extensive use.
RF range covers what matters in 2026. 20 MHz to 6 GHz covers WiFi (2.4 GHz and 5 GHz), 4G LTE, smart meters, Bluetooth, and most 5G sub-6 GHz deployments. The one thing it won’t catch is 5G mmWave (above 6 GHz) — but mmWave 5G has extremely limited range and penetration, and is not meaningfully present in Australian residential environments yet.
What Could Be Better
No dirty electricity measurement. Dirty electricity — high-frequency voltage spikes riding on the 50Hz power line — is a distinct EMF concern that the TF2 doesn’t address. You’d need a dedicated line EMI meter (like the Stetzerizer or Graham-Stetzer) for that. For most home audits the TF2 is sufficient, but it’s worth knowing the gap.
No data logging. The TF2 has a peak hold function but no data logging or Bluetooth connectivity. You’re writing numbers down by hand during an audit. This doesn’t affect measurement quality but it’s a friction point in a detailed room-by-room assessment. Higher-end instruments handle this better.
US shipping. AlphaLab ships the TF2 internationally including to Australia. Delivery is typically 10–14 business days to QLD. It’s available through Amazon AU at a modest price premium over direct — the trade-off is faster shipping and local returns handling.
How It Compares
| Meter | Magnetic | Electric | RF | 3-Axis | Price (AUD) |
|---|---|---|---|---|---|
| TriField TF2 ★ | ✓ | ✓ | ✓ | ✓ | ~$220 |
| Cornet ED88T Plus | ✓ | ✓ | ✓ | — | ~$180 |
| Acousticom 2 | — | — | ✓ | — | ~$250 |
| Sub-$50 detectors | ~ | — | — | — | ~$30–50 |
The Cornet ED88T Plus is a legitimate alternative at a slightly lower price point. Its RF sensitivity is competitive and it covers all three field types. What it lacks is three-axis magnetic sensing and the frequency-weighted mode. For a first meter it’s a reasonable choice. For a serious home audit the TF2 is the better instrument.
The Acousticom 2 is an RF-only meter with exceptional sensitivity — building biologists often carry both a TF2 and an Acousticom 2. If RF is your primary concern and you want the most sensitive possible measurement, the Acousticom is worth considering as a complement. As a first and only meter, the TF2 is more practical.
Final Verdict
The TriField TF2 is the right meter for a thorough Australian home audit. It’s the instrument I use, it’s the instrument building biology professionals use, and it covers the measurement range that matters in a modern residential environment. The price is reasonable for what it does. The one limitation worth knowing about is the dirty electricity gap — if that’s a specific concern, budget for a dedicated line EMI meter as a companion.

Frequently Asked Questions
Is the TriField TF2 available in Australia?
Yes. The TF2 ships internationally from AlphaLab Inc in the US, with delivery to Australia typically 10–14 business days. It’s also available through Amazon AU with faster domestic shipping at a modest price premium.
What does the TriField TF2 measure?
Three types of electromagnetic fields: AC magnetic fields (40 Hz–100 kHz), AC electric fields (40 Hz–100 kHz), and radio frequency/microwave radiation (20 MHz–6 GHz). This covers power lines, wiring, appliances, WiFi, mobile phones, smart meters, and 4G/5G signals.
Does the TF2 measure 5G?
It measures sub-6 GHz 5G, which covers the majority of Australian 5G deployments. It does not measure 5G mmWave frequencies (above 6 GHz), which have very limited range and are not meaningfully present in Australian residential environments at this stage.
What’s a safe EMF reading on the TriField TF2?
There’s no universally agreed “safe” threshold — different bodies set different reference levels. The Building Biology Institute’s precautionary guidelines suggest below 0.1 mW/m² for RF in a sleeping area (no anomaly), with concern rising above 1 mW/m². For magnetic fields, below 0.2 mG is considered no concern in sleeping areas. These are precautionary guidelines, not regulatory limits.
Can the TF2 measure dirty electricity?
No. Dirty electricity — high-frequency voltage spikes on the AC power line — requires a dedicated line EMI meter such as the Stetzerizer or Graham-Stetzer filter meter. The TF2 covers the three main field types but not this specific category.
How accurate is the TriField TF2?
The TF2 is manufactured by AlphaLab Inc, a scientific instrument company based in Salt Lake City. It’s used by building biologists and environmental consultants and is considered a reliable professional instrument. It is not a calibrated laboratory reference instrument, but for home and occupational assessments it provides accurate, repeatable results.
