We are very excited to offer this simple and useful item for anyone who wants to monitor their EMF environment without having to stare at their meter for hour after hour. Carry it with you to alert you when you become exposed to more radiation that you want. 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. Same specifications as our Trifield Meter.

Since EMF's are nearly everywhere it may be impossible to totally avoid them. The SAFE RANGE EMF METER from K-II can help you measure these potentially harmful fields and determine the safe range to help reduce exposure. It also helps you determine which appliances produce high level emissions. 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 as well. Also known as the Safe Range Meter. Made in USA. Uses one 9V battery (included). Single Axis.

Ultra Low Frequency Spectrum AnalysisEquipment Set-Up for Analyzing Frequencies from 0-60 Hz
The voltage output from our Geomagnetometer (read more) provides excellent frequency information from low frequency signals. The amplified, unrectified, Hall effect probe output retains all the frequency information from the magnetic field under investigation. Simply connect the voltage output (3.5mm mono jack) from the Geomagnetometer to the oscilloscope or spectrum analyzer and monitor both field strength AND waveform, frequency, and spectrum distribution of your signals. Because the Geomagnetometer output produces 200 mV at full scale, you get plenty of signal to the oscilloscope or spectrum analyzer. For example, on the 0-2 mG range: 2 mG produces 200 mV output, .05 mG produces 5 mV. On the 0-200 mG range: 200 mG produces 200 mV output, 5 mG produces 5 mV. In our tests, the actual output range from the Geomagnetomer extends significantly beyond 200 mV, and was useful up to 60 Hz and beyond. Interested in .01 Hz? 2 Hz? 7.8 Hz? No problem! You can analyze fluctuations in the Earth's magnetic field, fields from audio recordings, and almost any other ultra-low frequency magnetic field source. Possibly biologic and paranormal sources?
Connect your computer to this meter's output to make a spectrum analyzer (with optional Spectrum Analyzer for PC)! You can even add the Audio Amplifier to boost weak signals.

VLF 3-axis Gaussmeter (Cat. #A1130) ……………….. $1495.00
These passive magnetic field sensors output AC voltage corresponding to the AC magnetic field strength. The frequency of the AC output voltage is the same as the frequency of the magnetic field. Single-axis, so it responds to fields parallel to the sensor axis. The sensor orientation shows the magnetic field polarization. No battery or power supply is needed. Connect to a display instrument (not included) such as AC voltmeter, oscilloscope or spectrum analyzer to display the output AC voltage and waveform information. These sensors have no minimum measurable field strength, so the sensitivity will depend on your display instrument. Maximum field: the sensor can be damaged above approximately 50 Volts output. Sensor includes operating instructions.

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!!
With the push of a button, this simple and accurate gaussmeter measures the level of
magnetic field emitted by all common electrical appliances and equipment. An easy to read
10 LED light bar scale gives readings from 1.5 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. EMF risk can be avoided if
you know where it is. If you are looking for a low cost, user-friendly meter, here it is!
AAA battery included.
This little meter measures the level of ELF magnetic field radiation from power lines, computers, kitchen appliances, and more! The easy to read scale, unique built-in audio signal and auto shut-off make it simple to use and a great way to find hidden sources of ELF frequency magnetic fields.
True-RMS 3 Axis AC Gaussmeter with all the features you could want. A real technological breakthrough.
This unique single axis meter is extremely easy to use and displays both total AC magnetic field plus levels with powerline frequencies and their harmonics removed. This allows the user to determine how much of the field is from normal man-made sources and how much is from other sources at a glance. Measure the field from a DC motor, or the fields inside your car without worries of contamination from powerlines. A great tool for looking for transient fields not associated with powerlines!
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 paranormal research in mind.
Lightweight and completely self contained, this easy to use gaussmeter from FW Bell is ideal for commercial or home use. Accurately measures Extremely Low Frequency Magnetic Fields generated by electrical equipment. Applications include detecting magnetic field emissions from a wide variety of sources, including video display terminals, AC power lines, office equipment, household appliances, and all types of electronic equipment. Look at these key features: 3˝ digit LCD display, Auto Range and Relative Mode. Selectable X, Y, or Z Axis plus Vector Summation, true RMS reading. User selectable Gauss or Tesla readout. Built-in software eliminates the need for complex calibration procedures. User prompts on the LCD allow fast, simple pushbutton operation. Low battery detection. Complete with instruction manual, soft carrying case, and four AAA batteries. USB interface allows power through the USB (cable not included), can also be powered by external 5VDC adapter (not included).

Very High Accuracy and Sensitivity
What this meter lacks in resolution it makes up with ease of use and very low cost. Will measure ELF/VLF magnetic fields in the frequency range of 20 - 10,000 Hz, with a minimum sensitivity of .25 mG. Laboratory tested and documented for accuracy.
Common ELF magnetic field frequencies are within the range of human hearing. This simple set up converts the AC magnetic signal directly into a dramatic corresponding sound signal. A 60 Hz powerline field sounds like a 60 Hz hum (a low note on piano keyboard). Harmonics can easily be heard, as well as clicks, static, and hash. LED displays are especially noisy. The strength of the field is proportional to loudness.
Analyzing frequency information from ultra-low frequency magnetic fields can be extremely challenging. Air coil type magnetic field probes just don't have the necessary sensitivity below about 20 Hz.
This chamber can be used with the Geomagnetometer to provide a zero gauss (magnetic field-free environment) reference, enabling you to take absolute readings of the ambient magnetic field (the Earth's magnetic field is typically around 500 mG). Concentric welded 12" long tubes (1" ID chamber) with stand, made of high permeability magnetic shielding alloy provide excellent shielding.
