Don't Touch That Live Wire!

A real low cost Electric Field detector for close proximity work! No numerical readout, but tells you if high E-fields are present or not. Audible tone and red LED when field is detected. Useful for detecting and tracing live wires or comparing E field from appliances.

This detector is ideal for electricians, maintenance staff, service and safety personnel and homeowners. It can detect voltages from 90V to 1000V AC. Built in LED light brightens work space in dark areas. Six inches long.

VOLTAGE DETECTOR - Compact size with pocket clip for convenience
- CAT IV, 1000V safety rating
- Operates on two “AAA” batteries (not included)

    Common uses:
  • locate live electrical wires
  • detect a break in an electric circuit (Christmas lights, extension cords)
  • check wires, fencing, appliances, fuses to see if they are energized
  • remotely check high voltage power lines and effectiveness of electric field shielding
  • check spark plugs and distributor wires of operating automobile engines
  • locate electric fields (such as cords, clocks, electric blankets) which may pose problems if too close to people and animals

E-Field Sensor Alarm


Extremely simple and effective electric field detector alerts user to the presence and strength of AC electric fields. Suitable for 50/60 Hz. Can distinguish 5 levels: <10, 10+, 40+, 80+, and 250+ V/m. Also provides audible tone whose loudness correlates with the strength of the electric field. Directional. Uses one 9V battery (not included).

Check for the presence of live wires, body voltage inducing electric fields, or broken circuits. Also, use it to demonstrate the effectiveness of electric field shielding. Compact 4.5 x 1.5 inches.

1-Axis Electric and Magnetic Field measurements Digital Combination Meter

The Digital Combination Meter boasts several distinct advantages for a meter in this price range:

  • Wide frequency response: very flat (1 dB) from 16 Hz to 2000 Hz; useful from 5 Hz to 7000 Hz (3 dB)
  • Tremendous Sensitivity and Range: Magnetic: 1-2000 nT (0.01-20.00 mG); Electric: 1-2000 V/m
  • Accuracy: ±2% ±20 digits at 50/60 Hz
  • Cool audio tone which resembles a Geiger counter
  • Simple to operate, easy to read.

Perfect for home, student, or researcher.
Uses a standard 9V battery, included. Instructions in German and English.

AC Electric Field Meter Reliable, Portable, Accurate

Providing RMS electric field strength readings over the frequency range of 5 Hz to 2 kHz, this handy meter does what no other meter in this price range can do. Two switchable ranges. Range 1 offers 20 V/m accuracy from 20 to 300 volts/meter and range 2 offers 0.1 kV/m accuracy from 0 to 10 kilovolts/meter. Simple to use, just set the dial to the desired range and take readings. Operates on a 9V battery which is included. Has a large analog display and comes with a complete 1 year warrantee.

As with any E-field sensing instrument, you will find that your readings are more accurate if you do not distort the ambient field with the presence of your body. Simply placing the meter on a stable (non-conductive) surface and backing away, or taping the meter to a 2 - 3 foot stick will allow you to move your body far enough out of the way to avoid distortion.

Now you can have accuracy in E-field measurements and affordability. Made in USA.

Electric Field Sensor

Antenna-type attachment for DMM which measures electric field in V/m & kV/m. Because electric fields occur whenever a voltage difference occurs, you can detect electric fields from appliances which are plugged in even if they are switched off. Unit produces 1 mV per V/m with 20% accuracy. Check outlets and electrical cords, especially in the bedroom. This sensor will determine the effectiveness of your electric shielding devices, and assist greatly in positioning your furniture. You will need a DMM which accepts banana jacks with 3/4" spacing. If you don't check, how will you know? (DMM sold separately).

Use your computer with this probe to make an ELF/VLF spectrum analyzer (with optional PC Based Oscilloscope)! You can even add the Audio Amplifier to boost weak signals. This has to be the lowest cost way to get high quality frequency information about your magnetic fields. Explore the mixture of frequencies commonly associated with common household sources, demonstrate harmonics, even compare shielding effects at various frequencies.
