PM2525 DMM
sophisticated higher resolution DMM, with good DC capability. Sadly, Ac is not so impressive, that's why it's only 4 stars.

A Wrinkle in Time + 3 additional
6 of 12 found this helpful While targeted at a younger audience, these books are quite extraordinary in terms of content and style, and can be enjoyed by anyone, just like Robert Heinlein's early books. The books in this quartet are adventures surrounding the unusual Murry family members, and manage to blend in everything from quantum physics to personal relations in an amazingly well-written and entertaining way.
These stories blend fantasy, science, religion, myths and the general issues of daily family life in a very positive way, and are an enjoyable read no matter what your background or age may be. I happened to pick up A wrinkle in time from our bookshelf (it belonged to our kids), and was so impressed, I tracked down the rest of the books to read them, a genuine pleasure.

Very Good Value EMF/Field Sniffer
2 of 2 found this helpful I have been searching for a simple tool to look for both stray RF and magnetic fields that was inexpensive, and this was surprisingly good. the sensitivity is high, and I could literally map the locations of emitting electronics within an LCD monitor, it was that sensitive. I cannot vouch for the field calibration, as I have nothing to accurately compare it to and it comes with no accuracy spec, but I did find it to be just what I was looking for, and it works to 3.5Ghz. Great and simple tool for trying to identify offending items around your workspace. the danger trip points seem realistic (40V/meter and 0.4uT), and it covers all common troublle items from LED lighting and monitors to cellphones and microwaves. it does not give the frequency of detected signals, but does distinguish between radiated and magnetic fields. I had no problem finding fields from items I knew were emitters.
