Measure EMF/ELF levels in milliGauss (mG) or microTesla (μT) up to 2000mG (200μT) with two ranges to choose from Built-in single axis sensor provides basic accuracy reading of ±5% 30 to 300Hz bandwidth Backlit display to view in dimly lit areas Data Hold and Min/Max functions

The Extech EMF510 measures energy from electromagnetic fields (EMF) and electrical signals and is sensitive to extremely low frequency levels (ELF). The built-in single-axis sensor is ideal for monitoring power lines, electrical appliances, fans and blowers, and electrical circuits in two ranges with milli-Gauss and micro-Tesla units. The EMF510 features a large backlit LCD for viewing in dimly lit areas, an ergonomic compact design with wrist strap, auto power off, and Min/Max function.
