Dave, I believe Applied Innovations makes a product like you are looking for. Their AIspy should do the trick, and works with all standard transducers, although a source for those escapes me at this moment. I was very impressed with this product. http://www.aiinet.com/ Mike Ventimiglia ----- Original Message ----- From: David Hares <[email protected]> To: Nathan Stratton <[email protected]>; Sean Donelan <[email protected]> Cc: <[email protected]>; Dzh-Marc <[email protected]> Sent: Tuesday, October 10, 2000 4:00 PM Subject: RE: Power monitoring Re: Power Outage in Chicago Loop > > I'll bite ... > > I've been looking for a unit that monitors just those parameters (voltage > and current on each phase as well as DC voltage, DC Current, temp, and > humidity) for the same reasons.
