Do you really want to spend thousands on this project?

The cheapest meter I found on-line (see link) goes for about a grand, and you would need to rig up a computer with it to record the data.

You only need a simple voltmeter to observe fluctuations, a stethoscope to listen to your amp's power transformer to see if harmonic distortion is bad enough to cause core saturation, and a portable AM radio tuned between stations to hear the effects of electrical noise inside your circuit breaker panel (requires removing the front cover).

If your fluctuations or distortion are bad enough to cause performance problems, then you might need a DC-blocker or regenerator. However, RF noise control can be done with cheaper filters.
