What is a Trifield EMF Meter?
The Trifield EMF Meter, especially the TF2 model, is a comprehensive device that measures three types of electromagnetic fields:
- Magnetic Fields: Low-frequency fields generated by electrical wiring, appliances, and power lines.
- Electric Fields: Low-frequency fields produced by voltage present in electrical devices and wiring.
- Radiofrequency Fields (RF): High-frequency fields emitted by wireless communication devices like cell phones, Wi-Fi routers, and microwave ovens.
The Trifield TF2 is designed to provide accurate measurements across all three types of EMFs with True RMS (Root Mean Square) capabilities, a weighted RF mode, and both digital and analog displays for easy reading.
Step-by-Step Guide to Using a Trifield EMF Meter
1. Familiarize Yourself with the Trifield EMF Meter
Before using the Trifield EMF Meter, take a few moments to familiarize yourself with its key features:
- Display: The Trifield TF2 features a dual display, with a digital LCD readout that shows precise numerical measurements and an analog needle display for visual feedback.
- Switch Modes: The meter has a mode switch on the front panel that allows you to select between different types of measurements: magnetic fields (0.1–100 mG or 0.01–10 µT), electric fields (1–1000 V/m), and RF fields (20 MHz to 6 GHz).
- Audio Button: An audio button activates an audible signal that varies in intensity based on the detected EMF level, helping you locate EMF sources.
- Backlight Button: This button turns on the backlight, making it easier to read the display in low-light conditions.
- Battery Compartment: Located at the back of the device, the battery compartment holds a 9V battery that powers the meter.
2. Power On the Trifield EMF Meter
To turn on the meter:
- Insert a fresh 9V battery into the battery compartment.
- Flip the mode switch to the desired measurement type (Magnetic, Electric, or RF).
- The display should light up, showing zeros or low baseline readings depending on the environment.

3. Select the Measurement Mode
The Trifield TF2 allows you to measure three types of EMFs. Choose the appropriate mode for your specific needs:
- Magnetic Field Mode: This mode is used to measure low-frequency magnetic fields. Set the mode switch to the Magnetic position. The meter will display readings in milligauss (mG) or microteslas (µT). Use this mode to check magnetic field exposure from electrical wiring, transformers, and household appliances.
- Electric Field Mode: To measure low-frequency electric fields, set the mode switch to the Electric position. The display will show readings in volts per meter (V/m). Use this mode to detect electric fields from electrical wiring, outlets, and devices.
- RF (Radiofrequency) Mode: To measure radiofrequency radiation, set the mode switch to the RF position. The display will show readings in milliwatts per square meter (mW/m²) or volts per meter (V/m). Use this mode to measure RF exposure from wireless devices like cell phones, Wi-Fi routers, and microwave ovens.

4. Take Measurements
Once you have selected the desired mode, you are ready to take measurements. Here’s how to do it:
- Magnetic and Electric Field Measurement:
- Hold the Trifield Meter in front of you at arm’s length, keeping it as steady as possible.
- Move the meter slowly around the area or object you are testing, keeping the meter aligned with the source of the field.
- Observe the readings on both the digital display and the analog needle. The meter will display the strength of the magnetic or electric field in real-time.
- If you have activated the audio function, listen for the audible signal, which increases in frequency as the field strength increases, helping you identify the source of EMF emissions.
- RF Field Measurement:
- Set the meter to the RF mode and hold it near potential sources of RF radiation, such as Wi-Fi routers, cell phones, or microwave ovens.
- Move the meter around the area, keeping it at different distances from the RF source to observe how the readings change.
- Pay attention to the RF Weighted mode, which adjusts the measurements to reflect human body absorption levels, giving you a better understanding of potential health risks.
- If you are measuring RF radiation outdoors, hold the meter in different directions to detect signals from cell towers, radio antennas, or other external sources.
5. Interpret the Readings
The Trifield EMF Meter displays measurements on both a digital screen and an analog needle gauge:
- Digital Display: Provides precise numerical readings of the detected EMF level. Pay attention to the units (mG, µT, V/m, mW/m²) to understand the type and strength of the field.
- Analog Needle: Offers a visual representation of the EMF level, with the needle moving in response to the detected field. This is useful for quickly identifying EMF “hot spots” or fluctuations in field strength.
6. Use the Audio Function to Locate EMF Sources
The audio function can help you locate the source of EMFs:
- Press the Audio Button to activate the audible signal. The meter will emit a sound that varies in frequency and intensity based on the detected EMF level.
- Move the meter around the area, listening for changes in the audio signal. A higher-pitched sound indicates stronger EMF levels.
- Use the audio feedback to narrow down the exact location of the EMF source.
7. Document Your Findings
Keep a log of the measurements for future reference or comparison:
- Record the location, date, time, and type of measurement (magnetic, electric, RF).
- Note any significant readings or observations, such as peak values or areas with high EMF levels.
- This documentation can be useful for tracking changes over time, identifying patterns, or sharing findings with professionals.
8. Turn Off the Meter and Store Properly
After completing your measurements:
- Turn off the meter by switching the mode dial to the Off position.
- Store the meter in a safe, dry place away from extreme temperatures or humidity to protect its sensitive sensors and electronics.
- Remove the battery if you do not plan to use the meter for an extended period, as this will prevent battery leakage and damage.
Tips for Effective Use of a Trifield EMF Meter
- Calibrate Regularly: Ensure your meter is calibrated correctly to maintain accuracy. Check the user manual or manufacturer’s website for recommended calibration intervals and instructions.
- Avoid Electromagnetic Interference: Keep the meter away from large metal objects or other sources of interference that could affect readings.
- Use Proper Technique: Hold the meter steady and avoid sudden movements to get stable and accurate readings.
- Measure at Different Distances: To understand exposure levels better, take readings at various distances from the source. EMF strength typically decreases with distance.
- Compare Results: Use the meter in different environments (indoors vs. outdoors) and near various sources to understand typical vs. high EMF levels.
Conclusion
The Trifield EMF Meter is a powerful tool for detecting and measuring electromagnetic fields in various settings. By understanding its features and following the steps outlined in this guide, you can effectively use the Trifield EMF Meter to assess EMF levels in your home, workplace, or other environments.
Whether you are a professional or a concerned individual, this meter provides valuable insights into EMF exposure and helps you make informed decisions about your surroundings.
