RF METERS
FOR DIGITAL & ANALOG SIGNALS
CELL PHONE DETECTOR
Palm size Camera / Mobile / Bug Detector with Superior Sensitivity
No need for professional electronic training or knowledge
Stop the disturbance of cellular phone communications within your desired control area. This unique detector will alert you to the presence of hidden remote cameras, RF bugs, cellular phone and other radio frequency devices. Avoid peeping or tapping to protect your privacy or protect information being disclosed secretly.
http://www.lessemf.com/images/a456.jpg Specially designed for easy and simple use, which does not require any complicated installation or any professional knowledge.
Features:
3 LEDs will light from Green to Yellow to Red, indicating the strength of detected signal.
Audible alarm: The alarm changes from Slow to Rapid indicating the strength of detected signal.
Superior sensitivity for longer detecting distance with an adjustable sensitivity tuner allows you to scan variable distance and can eliminate background interference
Operates on 2 AAA batteries (included) for portability. Improved features: now covers 50 MHz to 6.0 GHz, and offers superior sensitivity to digital and analog signals.
Applications:
Hospitals, medical centers or intensive care units, etc. that forbid cellular phone usage
Schools and testing facilites to prevent exam cheating while proctoring
Offices, factories, cinemas, theaters, concerts, museums or art galleries that prevent video body bugs.
Military, prison, or government premises where cellular or camera recording is forbidden.
Offices, restaurants or any commercial premises that would like to discourage cellular or RF disturbance.
Find the best signal spot for wireless CCTV or characterize antenna emission pattern.
Detect peeping cameras in shopping mall toilet, school toilet, locker room and fitting booth, club house, hotel etc. Can also be used to monitor the strength of cell phone towers, TV/radio broadcasts, wireless keyboards and mouse, and other strong communications signals from 50 MHz to 6 GHz.
BETTER RF METER
Budget Minded, Information Packed The meter represent both a price and technology breakthrough! Simple hand held meter is so easy to use: One button, just to turn it on/off! Uses ordinary 9V battery (not included). Very sensitive (down to 25mV/m = 0.16 nW/cm²) and goes as high as 14.8 V/m = 58 μW/cm². Broad frequency range too: 100MHz to 3.0GHz digital or analog signals. ±3.5dBm accuracy.
Look at all the information on the LCD screen:
Signal power level in dBm
Signal power density in μW/m², mW/m², or W/m² (automatic)
Horizontal bar “power level display” with 12 5dBm segments
Moving bargraph showing signal changes over the last 32 readings
8 segment LED bar (green/yellow/red) power indication
Backlit for first 10 seconds of display Truly unique tool for personal RF exposure detection and level measurement. Use it to check GSM, TDMA, CDMA, PCS, Wi-Fi plus AM/FM and TV signals and much more.
HIGH FREQUENCY METER
Calibrated, Directional, Accurate, Sensitive http://www.lessemf.com/images/a481.jpg
We like this calibrated wideband (800 MHz – 2.5 GHz) RF meter because it has a switch which allows a choice of peak or average indication mode. This permits accurate measurement of both digital and analog signals. Two ranges: 1 - 1999 µW/m² (same as 0.1 – 199.9 nW/cm²) and 0.1 - 199.9 µW/m² (same as 0.01 – 19.99 nW/cm²).
In addition, you get a choice of audio tone – none, or intensity proportional to field strength, or proportional to frequency (for analyzing pulsed signals)
- accuracy ±6 dB
- true logarithmic - periodic antenna, 800 MHz – 2.5 GHz, single polarized, included
- standard 9V battery included
Easily detects cell phone towers, cordless phones even microwave oven leaks. Instructions in German and English. 2 year Warranty. Model HF35C.
