ElectroSensor Electromagnetic Field Detector
Compact and easy-to-use, ElectroSensor is the quickest way to measure EMF levels. Simply push a button and the handheld unit’s bright, simple-to-read LED gauge lets you know within seconds whether there are electromagnetic fields in any area. A 10 LED light bar scale gives readings from 1.3 to 30 mG in small increments. A pickup coil in the tip of the unit can be rotated in both directions. This is great to keep in your pocket when your hands are filled up with other gadget:-) I carry this one around at every investigation. Requires 1 AAA battery (included). Only available in black.
