Andrew Next SEI class PV351L is in Aug, the cost is high , but they limit the instructor to student ratio to 1:4 and the entier class to 12 people to make sure

We have been using the Flir i7 for many years. I can also attest to the fact that it is a relatively inexpensive tool that should be in your kit. The more you can document, the better, when going for warranty replacements. Or, even better yet, providing the math and physics proof the module is work

Jason Accuracy of measurements is dependent on the size of the hotspot and the circle in the bulls eye of the camera, see the module attached to Randy's response. The big problem with the less expensive cameras is that ratio is totally distance dependent, and you need to get really close to get a

I've been considering this for solar thermal (pool heating) applications. Any comments on how far away these can be effective? For example, what if I am 30 feet away, trying to diagnose a flow rate issue through a large array of panels? I would need to get far enough away to get the whole system in

Andrew I highly recommend any of the fluke E series. Better resolution and you can get accurate temperature measurements at a safe distance from live circuits. IMHO , any lower model, you will wish you could do more! I also recommend Solar Energy International's Advanced tools lab, a week of han

Andrew, Have a look at the Fluke VT02. The screen is small, but it is designed for electrical troubleshooting, has a nice IR/visual mix feature, image capture, and is less than $1,000. Jeff Irish Hudson Solar From: re-wrenches-boun...@lists.re-wrenches.org [mailto:re-wrenches-boun...@lists.r

Bosch and Milwalkee Tool have them, I have seen them advertized and demonstrated on a mock roof, They work reliably with one layer of asphalt shingles, not with two. The cheap ones do not work. these are ultra sound I think. Darryl --- On Mon, 8/30/10, Gary Easton wrote: > From: Gary Easto
