Hear What You Have Been Exposed To
A new, inexpensive hand-held device available to the consumer which can detect the pulsing emissions from wireless communications technologies (mobile phones, masts, DECT digital cordless phones, w/LAN’s, Wi-Fi, etc.) which are considered by scientists to be the cause of health effects among a significant minority of the population. The Electrosmog Detector enables you to judge the relative levels of such pollution by listening to both the volume and quality of the sound. GSM, 3G, wLANS, DECT digital cordless phones etc all sound different and after a little practice are easy to identify. The Electrosmog Detector enables you to ‘hear’ the electrosmog that exists all around you. The level and quality of the sound emitted is directly related to the type and intensity of man-made microwave radiation. It is not an alarm, nor is it a warning device. It is an educational tool providing an awareness of your personal environment. Curved design fits comfortably in the hand and requires no technical knowledge to operate. The Electrosmog Detector is the first true consumer product in this category.
Detect the electrosmog ‘hotspots’ in your environment and protect your family anywhere that you spend time - at home, in offices, schools, libraries, hotels, restaurants and when travelling. Has a built-in speaker, 2.5 mm mono headset jack for private operation (headset not included) and 2 year warranty. Uses 9V battery (included). Patented. 2 yr mfr wty.

MicroAlert is an alarm that you wear like a pager that will alert you to the presence of radiofrequency and microwave radiation. The MicroAlert is important protection for all pacemaker users, those sensitive to RF radiation from TV or cell phone broadcasts, or anyone who lives or works in the presence of microwave or RF hazards. Can even be used to detect audio and video transmission from concealed bugs or the unauthorized use of cellular phones! MicroAlert will respond to as little as 0.1 µW/cm² in highest sensitivity mode. When MicroAlert is moved closer to the source of RF radiation, the chirps will become more frequent, and will become a solid tone when exposure is high. Responds to frequencies from 500 kHz to 3 GHz, although response is not flat over this range. What this means is that at any given setting, the threshold will vary with frequency. Note: This is not a high precision meter. Sensitivity information is only a guideline. The beeping alarm threshold can be adjusted from no threshold (constant beeping regardless of radiation exposure), to to a maximum of about 10 microWatts/cm². It is intended to be an alarm for cell phones, cell towers, microwave ovens, surveillance bugs, and most RF transmitters. Only 1-5/8" x 2-1/4", the 1 oz. MicroAlert uses one Lithium coin cell #2032 which should last about 3 years with normal use. Includes convenient belt clip. 1 year mfr. warrantee.

Consider one of these COMBINATION METERS: Trifield Meter • Trifield Extended Range Meter • Natural EM Meter
At this price, you can't beat the Zap Checker as a relative field strength meter. It has tremendous sensitivity and very broad band. Most RF meters use a microwave diode detector as a basis of their detection system. They work well at high signal levels, but have limitations at lower signal levels. The Zap Checker's innovative design uses several stages of RF amplification before detection, thereby making it more like a broad-band receiver than a field strength meter. The useable bandwidth extends from 3 MHz to more than 5 GHz, and can detect even weak transmissions from surprisingly long distances, or pinpoint leakage in cables, locate hidden transmitters, determine optimum placement of computer wireless equipment, monitor radiation levels at the baby's crib, detect hidden cameras, audio bugs, and more. Detects digital and analog signals. A manually adjustable sensitivity control allows you to adjust the gain. Zap Checker has fixed internal antennas. Detection is in logarithmic or linear modes. Use the logarithmic mode for stronger signals In linear mode, the Zap checker picks up the weakest signals for full display. The signal reading is either by analog meter or illumination of colored LED's. The Zap Checker also has a switch enabled silent vibrator mode for situations in which it is undesirable to view the displays directly. Zap Checker uses two AA batteries (not included) for more than 80 hours of use and weighs less than 5 oz.
