Customer Reviews

Great meter
This is a great little meter; solid and well-made. I use it for measuring EMF around the house. The reason I don't give it 5 stars is that it doesn't come with any information about how to use it - I have used an EMF meter before so I know what kind of fields to expect, the need to rotate the meter sometimes to catch the fields, and etc. But if I didn't already know this, it would be a problem. The meter also has an ELF setting and I don't know anything about that.

Good meter, lousy company.
I like the meter, it found several hotspots in our house almost immediately. For that I consider it a priceless addition to the home to keep EMF levels under control. In addition, this meter prompted relocation of the kids beds away from a medium level EMF source (power meter on outside wall).

3 emails to the company for tech support remain unanswered, so don't count on any responses or support from this company. For that I am deducting 1 full star. When will these companies learn that they need to actually respond to their customer emails if they want continued business?

Very good handheld Gauss meter
I used this gaussmeter to check the magnetic fields for installing a scanning electron microscope (SEM). Fields over 0.5 Gauss can cause problems in imaging using SEM. This meter was of very good help in the preliminary check for the fields. Some times this meter was too sensitive but it is OK (cross calibaration using a multi-thousand dollar gauss meter by a professional).

At 75$, I strongly recommend this product for testing any fields as low as 0.5 gauss.
