Measuring line noise and power conditioners

I recently purchased a Trifield EMI (Dirty Electricity) Line Meter to measure noise coming from my outlets. To my surprise, my $500 power conditioner (name withheld to protect the potentially innocent) appears to not filter any noise per the Trifield readings. In fact, with some of my outlets the measures are higher through the conditioner’s outlets, than the measures coming straight out of the wall. The manufacturer denies anything is wrong with their conditioner, claiming the Trifield is measuring the wrong frequencies. Can anyone explain?

@geoffkait ,

Always appreciate your enlightment.

Of coarse, the logic in me would say, if these two terms are "the same thing", why are there two terms?

@erik_squires ,

Now you seem to be backing off your original post.

I never said I'm done. Just reporting my experience.

@tvad ,

That's really high my friend. Mine on either dedicated line is now measuring around 220.
When you achieve a lower level, you will be surprised at the increase in SQ.

In your recent responses, you say RFI. We are referring to EMI.

What I hear ain't luck. Having a device that can measure what I hear ain't luck.

What’s wrong with that?.

Frankly, I heard a substantial improvement in SQ, then I realized I had the meter. It seemed to confirm, In a measurable way, the increase in SQ I was experiencing.

Hi,
I have nothing to compare it to. It was expensive. However, it's a nice piece to have.

I recently put a Hydra 8 into my system. Measured EMI with my Alpha Labs meter and EMI noise was cut in half.
