EMF Meters

Select an EMF meter based on the field types you need to measure (magnetic, electric, radiofrequency), the frequency range it covers, required sensitivity, and whether you need features like data logging, weighted exposure units (mG/µT for magnetic, V/m for electric/RF), or a portable form factor

EMF meters in this category commonly range from budget handheld models under $50 to more advanced or calibrated instruments above $150, with an average price around $75; choose based on required accuracy, frequency coverage, and build quality

Compare frequency range, measurement type (AC magnetic, AC electric, RF), sensitivity/accuracy, display/readout resolution, calibration status or traceability, and additional features like peak hold, data logging, or alarms

No single meter measures every signal equally; broadband meters detect aggregate RF energy while spectrum-specific or frequency-selective instruments are needed to identify or measure specific wireless bands accurately

Keep the meter clean and stored in a dry, temperature-stable place, replace batteries as recommended, and follow the manufacturer's calibration guidance—periodic professional calibration or comparison to a reference standard is advised for precision work

Hold or position the sensor according to the meter's user manual, avoid proximity to large metal objects that can distort fields, measure at multiple locations and heights for representative readings, and note conditions (device states, distances) when recording results

Choose units appropriate to the field type—mG or µT for magnetic flux density, V/m for electric and RF field strength—and be aware that some meters apply weighting or different frequency responses that affect direct comparability of readings from different devices
