If you are looking for hidden espionage devices you do a raster scan moving this instrument across the surface of the walls, floor, and ceiling of your room. Then over all of the surfaces of the objects in the room. This still will not get all of the devices because they can be remotely controlled to turn on and off to save battery power.
If you do a google search for 'field strength meter' you will get at the top of the list hobby grade ones with low cost.
They are different words for much the same thing. Field strength meters used in industry are calibrated for strength in volts/meter. Since all you want to do is discover espionage bugs, knowing the exact stength is not necessary.
