http://www.aemc.com/ 3945 Power Quality Analyzers

I dont' have anything to do with this company - however I got an ad in the mail
at work -

Three phase hand held waveform and power quality analyzer. Looks very interesting.

Pdf documents on-line.

# True RMS single-, two- and three-phase measurements at 256 samples/cycle, plus DC
# Real-time color waveforms
# Easy-to-use on-screen setup
# True RMS voltage and current measurements
# Measures DC volts, amps and power
# Display and capture voltage, current and harmonics to the 50th order, including direction in real time
# Phasor Diagram Display
# VA, VAR and W per phase and total
# KVAh, VARh and kWh
# Neutral current display for three-phase
# Transformer K-factor display
# Power Factor displacement PF display
# Captures up to 50 transients
# Short-term flicker display
# Phase unbalance (current and voltage)
# Harmonic Distortion (total and individual)

Looks good - I have not seen the price - suspect it is not hobby level.
