I am trying to determine the right EMF meter for my home. I was going to purchase the Trifield TR2, but I decided to research the budget market to find the best meter. I was pleasantly surprised to discover the GQ EMF 380, but now I am trying to evaluate this meter's accuracy, so I was wondering how the Advanced EMF-380 compares to the TriField TR2? I found the following specifications for each meter, but I am having trouble trying to determine which meter is more accurate. The V/m resolution appears to be more granular for the EMF-380, but it is difficult to understand since the TriField manufacture doesn't specify accuracy using the same format. For example, Electric Field measurements of the EMF-380 specifies "10%+50dgt" but the TR2 reports "5% @ 50/60 Hz". Is the TR2 meter generally more accurate?

What are your thoughts?

a 5% difference in accuracy is not that much because it's hard to measure the exact EMF value at a fixed position/place.
But the EMF 380 has a lot of functions that the TF2 doesn't have like The 2.4G WiFi Spectrum, 60second graph, etc.
