RF detector with Sound
The MicroAlert™ 2
radio/microwave alarm is a pocket size detector ideal for anyone trying to find out exactly what's emitting radio
or microwaves, including hidden sources.
A clear, loud beep indicates radio waves stronger than the level you select. If you move closer to the radio
source, the beep becomes more frequent, and will ultimately become a solid tone if you move closer still. Or, if
you move away from the source, the beeping will stop. Minimum sensitivity is .001 milliwatt per cm2,
making it much more sensitive than the radio/microwave section of the TriField® Meter.
At the highest sensitivity, it will detect a typical cellular phone tower within 300 feet
line-of-site, a typical analog cell phone 40 feet away, a digital phone 20 feet away, and a microwave oven
(in use) 10-50 feet away. However, you will usually use a less sensitive setting. It's most sensitive from 100 MHz
- 3 GHz, so ordinary cordless phones do not cause much interference (detectable at about 2 feet).
The switch on top lets you select standard sensitivity, high sensitivity or "off". In addition, a control on the
side can raise or lower the overall sensitivity. The unit chirps once each time you turn it on to indicate that the
battery is good. With the sensitivity on "high", you'll be surprised at the places (and times) you find
The unit comes with a 3-volt lithium coin battery, which has a typical life of 3 years (assuming it "beeps" with
a typical 10% duty cycle for 10 minutes a day) or a 6-year life if it very rarely beeps. The replacement battery
(Lithium type 2032) is available at most drug stores.
