- Band covered
- power frequency plus harmonics
- Quantities measured
- body voltage
- Typical price
- $80–$300
Detects
- Capacitive coupling from nearby energised wiring to the body
- The effect of unplugging individual devices, one at a time
- Whether a demand switch or shielded cable actually worked
Cannot detect
- Magnetic fields
- Radiofrequency fields
- Anything comparable between homes unless the same grounding reference and protocol are used
What to insist on
- Input impedance high enough not to load the measurement, typically ≥10 MΩ
- A defined ground reference: protective earth or a dedicated ground rod, documented in the report
- AC millivolt range with 1 mV resolution
