Measuring radio frequency and microwave radiation has never been easier! This unit covers the amazing range of DC - 12 GHz and will give you digital readout of the relative field strength of broadcast signals such as cellular phone, microwave oven leakage, TV station, CB radios using the (1MHz - 1GHz) telescoping antenna provided. Can also be used to measure 60 Hz electric field signal from powerlines and wiring. Even use it as an RF safety monitor! Adjusting the length of the antenna will affect the signal gain. Other antennas (not included) can be obtained for extended frequency ranges.
Can also be used to make relative power measurements (and determine power loss) of single frequency coaxial sources such as cable TV, and with simple adapters, this meter may also be connected directly to any receiving antenna to measure signal strength while the antenna is tuned, modified or repositioned.
Includes an ACV output (3.5 mm mono) which allows user to log spectrum/intensity data to a remote device.
Large 3˝ digit LCD readout is easy to see. Only 3" x 4" x 1˝" and weighs less than a pound, this is good value for checking high frequency radiation sources, tuning or modifying broadcast antennas, or testing the effectiveness of your RF shielding. Powered by a standard 9V battery which is included. 1 year mfr. warranty. Made in USA.

In addition to measuring changes in extremely weak static (DC or "natural") electric and magnetic fields, the NATURAL EM METER gives a readout of radio/microwave signal strength in mW/cm˛ and has and audible alarm. The threshold of the alarm can be set at any level from 0.01 mW/cm˛ to 1 mW/cm˛. Using both a needle type meter and audible tone, it detects: radio transmitters, geomagnetic storms, unusual magnetic solar activity, electrical activity of thunderstorms, leaky microwave ovens, magnetized rocks or bed frames, analog cellular phone EMF output, and concealed surveillance bugs. Perfect low cost RF alarm for those working near RF equipment and antennas. RF sensitive down to 0.01 mW/cm˛, with a full needle deflection at 1 mW/cm˛ over the frequency range of 100 kHz to 2.5 GHz. 9v battery included. One year manufacturer's warrantee.
Make some waves! Need a source of 20 Hz to 150 kHz frequencies? Handy little unit fits in your shirt pocket and is very simple to operate. Produces nice clean sine waves (adjustable intensity up to 1.2V rms) or square waves (p to 8V p-p) with 5% frequency accuracy. Simply dial in the desired frequency. Uses 9V battery (50 hrs typical use). Includes low battery indicator, test leads and 9V battery.
Check the response of your gaussmeter to various frequencies (connect the Frequency Generator to the Degaussing Coil to generate several mG fields at various frequencies), test your frequency counter, connect to a speaker/headphones to test your hearing range! Also great for field/bench service of audio equipment, car stereo, etc. Bargain price!
