The Cell Sensor electromagnetic field detector will let you know if you’re in danger of frying your body in an over-abundance of electrical radiation. The type of stuff that comes from phones, computers, televisions and just about everything fun that we own. It’s a tough life… $39.95.
The compact meter is ideal for detecting both Electromagnetic Fields (EMFs) and Radio Frequency (RF) radiation. Easy-to-read analog meter (registering mW/cm2 for RF and milliGauss for EMF), flashing LED and audio alarm make it quick and simple to identify emissions from cellular phones, computer monitors, TVs, and more.
I bought one of these one Ebay and find that the device is much more sensetive when using the probe. Which reading is more accurate, and what's the scale when using the probe?
