I was curious if I could detect any high level EM radiation coming from either of our electric vehicles, especially my home-made Geo EV. Unlike a Nissan Leaf (or any commercially made EV), my Geo EV did not go through extensive EMI testing and certification.
I would expect to detect at least some field reading but surprisingly, no matter how aggressive or gentle I was on the throttle, from inside the cab of the Geo EV (even with 300+ amps going through its DC brushed motor), I was not able to get the meter to even register a reading. It must be the additional shielding brought on by the car’s metal uni-body construction. A Faraday cage. Cool!
The meter does indeed work though. I confirmed that it could detect a field coming from various household appliances (a rice cooker, a cell phone, a hair drier, florescent lights, cooling fan and electrical wires inside the walls of our home).
This meter also serves as a valuable tool to locate live wires when doing remodeling.
I was not able to detect anything coming from our LCD TV or LED computer monitor. Gone are the days of the low-level radio and X-ray emitting CRT screens.
As an electrical engineer with an emphasis in electromagnetic fields, it is my professional understanding that this meter only measures the electrical field component and not the magnetic field. and only in the frequencies specified. As such, you will not detect radioactive sources or any other shorter wavelength EM radiation. Basically just stuff in the radio spectrum.Read more ›
I was looking for a piece of actual scientific equipment, not something one might see on "Ghost Hunters". I will definitely be sending this back
Pros: less expensive than other meters; lightweight; appears to respond to emf
Cons: flimsy plastic; no decimal point on digital readout(but common sense tells you where it should be); unsure how accurate it is
In any case I think this is a pretty good deal for the price. The meter is useful around the house and is a relatively inexpensive addition to any paranormal investigation kit.
It's obviously made in china, but instructions are in both English & Chinese. It's easy to figure out.
I tested this device against the pre measured known areas in the observatory. For household wiring, known "dirty electricity" areas, there was no response. For a nearby cell phone tower, no response. For a cell telephone on standby as well as initiating a call, no response. Twelve inches from a running 1500 W microwave oven, no response. The only reading that registered was about 18" from a running motor in an air purifier. The reading went to 0 farther away. By comparison other measurements show that biologically active intensities exist for a six foot radius around the air purifier.
This device is not sensitive enough in frequency response or sensitivity to be of value to detect possibly biologically active signals and protect people. There are other inexpensive devices such as the iMeshbean that work much better.
I'm returning this one.
