The RFID Power Mapper is a pocket size device that helps to map an RF field up to 15 meters (49 feet) in range for an RFID application. Only using RF power, this device is very sensitive and is capable of showing constructive and destructive interference patterns caused by multipath. It works with all known European and US UHF RFID readers and can indicate to the user where a Gen2 tag may or may not be readable. With the RFMAX Power Mapper you're no longer working in the dark. This meter is specially designed to show nulls in the UHF radio field at large distances from the antenna. You will find it hard to believe how large the signal variation can be, even quite close to the antenna. The meter will show polarization effects and destructive null cancelations, ground and water absorption. The meter relies on the power in the radio waves, so it cannot give a fails reading or have a flat battery. Almost 100% of the signal on at the antenna is shown on the meter, giving a massive 10+ meters (30+ feet) range.
This product will help take some of the guess-work out of your RFID system by indicating read zones, null zones, as well as constructive interference areas.

I'm a race timer. I use this little meter at every single race to test my antennas, and assure that the entire finish line has RFID coverage. It works perfectly.
