Trifield 100XE ($199.95) - EMF Meter for Australian Frequency 50Hz (Magnetic and Electric Fields)


FREE Safety Reference Leaflet by EMF Safe to determine if readings are low to high based on
strict European guidelines and up-to-date scientific studies.
Australia-Wide Registered Post: $9.95


  • High sensitivity and accuracy detection of electrical radiation (magnetic and electric fields) from power lines, substations, meter boxes, electrical wiring and electrical equipment
  • Low sensitivity detection (see below) of wireless radiation (RF fields) from mobile phones, cordless phones (DECT & analog), wireless internet (Wi-Fi), baby monitors, mobile towers, game consoles (Xbox, Playstation, Wii etc), tablet computers, microwave ovens
  • Measures EMF pollution from electrical and wireless "hot spots" in your home, office or work environment so you can take steps for "prudent avoidance"
  • Extremely easy to use.


  • 50Hz model compatible with Australian electricity (NOTE: most Trifield 100XE devices sold online are not suitable for Australian conditions)
  • Electrical and wireless radiation detection (magnetic, electric, and radio) all in one package
  • Omni-directional (tri-axis/3-axis) electric and magnetic readings for high sensitivity
  • Hand-held portability and simplicity
  • Meter combines all these unique features with affordable pricing for fast, reliable measurements of EMF radiation: Continuous sampling analog readout; Omni-directional electric and magnetic sensitivity; Two separate scales for magnetic field readings; Hand-held portability and simplicity.
  • Made in the USA.



The Trifield Meter is a gaussmeter, electric field meter and radio field strength meter in a single unit. When measuring electrical radiation, the primary concern is usually magnetic fields which can be tricky to measure. If a less sophisticated 1-axis gaussmeter is used, a reading of zero could result even where the field is strong. A 1-axis meter must be oriented correctly to measure the field (which is a vector). The 3-axis Trifield Meter solves that problem by measuring the true strength of the field regardless of which way it is oriented. Therefore, the Trifield Meter can be scanned rapidly across an area without having to stop at each point to search for the orientation that gives a maximum reading. Another section of the meter detects AC electric fields, which can exist independently of AC magnetic field.
The third section detects wireless radiation such as from Wi-Fi, mobile phones, cordless phones etc. Analogue (needle-type) display has very fast response time compared to digital. This meter is good for measuring AC (artificial) magnetic fields rapidly, AC electric fields rapidly. Can locate wiring in walls and major wireless radiation (RF/microwave) sources. Operates about 40 hours on replaceable standard 9V battery (included) and has a low battery indicator.

EMF Safe Commentary

At EMF Safe we've tested many meters of the years. The Trifield 100XE is one of our top meter recommendations.

  • Ease of use - turn the knob and read the dial. If the needle sits in the dotted red line the reading is low. If the needle sits in the solid red line the reading is high.
  • Very good gaussmeter function (electrical radiation) - can measure magnetic fields from 0.2 mG up to 100 mG. Most meters in this price are unable to match the 100XE's broad frequency range and high degree of sensitivity and accuracy.
  • Low sensitivity RF function (wireless radiation) - whilst acceptable for providing an indication of wireless radiation levels it is not as sensitive as dedicated RF meters. For example, measuring Wi-Fi and mobile phone tower radiation may not be detectable with the Trifield Meter unless very near to the source.
  • Price - unbeatable value for money. Whilst the device does have some limitations, the Trifield 100XE EMF meter offers a very broad level of functionality for the money.
  • Excellent user reviews - many online reviews from happy owners pay testimony to this excellent meter.
