The MicroAlert™ radio/microwave alarm is the size of a small pager. It is ideal for anyone trying to find out exactly whats emitting radio or microwaves, including hidden sources. Just turn it on, select the sensitivity level you want, and put it in your purse or pocket. [Actual size is 56 mm high x 40 mm wide x 19 mm thick.]
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.
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.
