Who sells decent current probes?
I'm looking for a clamp-on current probe. I'm willing to settle
for
betterthan stellar accuracy (+/-5% would be close enough), but it has to
work down to DC. A range of 0-20A would be sufficient for now, but
more is better if I can switch ranges.
A quick perusal of Tucker Equipment sales got lots of hits, at
disappointing prices.
TIA.

You might try BellNorthWest since you're in the area. The prices seem
than Tuckers and they're just North of the Portland area inModel
Washington.

We just bought one of the older Tek Current Probes. Don't remember
the
number, it's at work.

I have several of the Tek model 610 (If I remember the # right). All
current probes (clamp on type) that I have researched use Hall sensors
for DC. If you only need AC, I suggest going with the CT type. The Tek
worked great until we went overcurrent on a test. It destroyed three
of our four probes! Fried the Hall sensors. I have not been able to
find a replacement for the sensor and Tek support says it's not worth
fixing! 3* $600, maybe not worth it to them!!!
TEK "support" has really slipped in the last 10-15 years.
I used to repair P6042 and A6302/6303 current probes while at TEK.
(their probe xfmrs were TEK-made,thus costly and not available elsewhere.)
