Extech Electromagnetic Field meter
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 miligauss 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.
Measure EMF/ELF levels in miligauss (mG) or microamps (μT) up to 2000 mg (200μT) with two ranges to choose from
Built-in single axis sensor provides basic accuracy reading of ±5%
30 to 300Hz bandwidth
