Extech EMF510 EMF and ELF Tester

A multi-function electromagnetic and electrical frequency measuring device like Extech’s EMF510 can be used to monitor anything from household appliances to electrical circuits. The EMF510 Meter can measure EMF and ELF levels in either milligauss (mG) or microTesla (μT) units, both of which can be set by the user. In addition to taking highly accurate electromagnetic and electrical frequency measurements, the EMF510 EMF/ELF Meter also offers Data Hold and Min/Max functions, features that can be useful when analyzing the data. The backlit LCD display allows measurements to be taken in low-light environments, and the optional tripod mount permits hands-free operation for lengthy measurement periods.
