Price:    $59.90

As Seen on all the ghost hunting TV shows

This genuine K-II can measure the EMF (Electro-Magnetic Field) radiation strength of 'unexplained electromagentic phenomena' during paranormal research, as well as electrical devices in your home, workplace or school, outdoor power lines, underground lines and even when you travel and shop for appliances.

Simply Push "ON" and push "OFF" to control the unit. The unit stays on until you push again. Couldn’t be easier.

Five bright colored LEDs will illuminate to indicate the strength of the field. Very easy to see in low light conditions. Response is instantaneous. No bouncing needle or fluctuating number digits. These features make the K-II very popular for paranormal research and ghost hunting.

An EMF meter designed for Paranormal Research

In paranormal research, the presence of man-made 50 or 60 Hz EMF signals can give rise to "false" readings. Wouldn't it be great if you could set your EMF meter to ignore these ever-present signals and just pick up everything else?

Now you can! With this meter you can look at just the 50/60 Hz signal, or just the harmonics, or just everything else. And you can compare that reading to the overall reading on the same screen at the same time! Adjustable back light too, because it was designed with ghost hunting in mind.

Also perfect as an all purpose True-RMS 3-Axis meter with high sensitivity. Great for distinguishing a 50 or 60 Hz signal from the higher frequency harmonic signals which often accompany power line magnetic fields.

Flat frequency response:

  • ±½dB 30 to 5000 Hz
  • -3dB 15 to 5500 Hz
  • Range 0-250 mG on any axis
  • Maximum resolution 0.01 mG

More Features:

  • Selectable axis (3D, X, Y, Z) on ALL features
  • Two display styles:
    • On-Screen Graph: select any of 3 values: total RMS, notched, bandpassed
    • Digital readout: RMS broadband plus select:
    • 60Hz only, or 60Hz+Harmonics, or 50Hz, or 50Hz+Harmonics
  • Variable Brightness Blue LED Backlight
  • Max Hold of any of the 3 values
  • Selectable units: milliGauss or microTesla
  • Low battery indicator

Alkaline battery (included) typically lasts ~20 hours at default backlight setting. Feature rich and easy to use, same meter works for both 50 or 60 Hz. Great price too! 1 year wty. Made in USA.

Personal EMF Alarm

Alarms at the Presence of Field Disturbances! The Trifield Meter with sound.

What could be better than a meter which alerts you with a loud audible alarm when it encounters a field? How about a meter which allows you to set the sensitivity of the alarm? How about a 3-axis meter? How about a meter which does all this for AC magnetic fields, AC electric fields, and RF radiation?! This meter does all that, for under $200!!

We are very excited to offer this simple and useful ghost hunting instrument for anyone who wants to monitor the EMF environment without having to stare at the meter for extended periods of time. Carry it with you to alert you when you encounter variations in the electromagnetic field (EMF).

Set it in a strategic location to alert you when a field trips the alarm. You set the level (threshold) above which the alarm will sound. Can also be used as a nice analog meter to read field strength.


  • Audible alert with adjustable EMF threshold
  • Easy-to-see large analog readout
  • 3-axis electric & magnetic sensitivity for fast surveys
  • Two (2) separate scales for magnetic field readings
  • Hand-held portability and simplicity
  • Extremely wide frequency response

Completely self-contained. Nothing else to buy, no parts to lose. 9V battery included.


Cat No.:    G144
Price:    $29.95

The Smallest Gaussmeter We Could Find!

With the push of a button, this simple and accurate gaussmeter measures the level of magnetic field emitted by all 'unknown sources', common electrical appliances and equipment. An easy to read 10 LED light bar scale gives readings from 1.3 to 30 mG in small increments.

The ElectroSensor has a detection range of 50-60 Hz with an accuracy of ±3dB. A pickup coil in the tip of the unit can be rotated for increased directionality.

EMFs easily found. If you are looking for a low cost, user-friendly meter, here it is! AAA battery included. We like this meter as an alternative to the K-2 (K-II) meter - it's smaller and it costs much less!
