What is an IR window? Basically it is a crystal lens that allows broadband infrared waves to pass through it (as well as visible light). The lens does not however allow electrical current to pass through. This enables the thermographer to take IR and visible images of live and energized electrical equipment.
Today I will be discussing the Extech CT70 AC Circuit Load and Outlet Tester. This circuit load tester may be small, but it packs a big punch. The first thing you notice about this load and outlet tester is the digital display. This innovation is oddly late to the party but makes life so much easier. When using the CT70 as an outlet tester the display will shine Blue for Pass and Red if there is a problem. The outlet functions that it handles are as follows,
Today we’re going to talk about a tool that, as far as I know, has no current competition or comparable product on the market – the Fluke VT02. While it has its limitations, it is certainly one of the best and most cost-effective choices for certain applications.
AEMC PEL 100 series power meters (PEL 102 and PEL 103) do everything you would expect out of a high quality meter in this price range with a few super cool features that place them above the competition in certain areas. First off, these loggers will take readings on single, dual, and 3 phase circuits in VA, W, and var for power and VAh, Wh and varh for energy and are designed for use in 1000V Cat III and 600V CAT IV environments.
It’s after 10pm, do you know where your kilowatt hours are?? Now you can find out with the Dent Instruments ELITEpro XC. This little meter packs a big punch into a small unit and does virtually everything you need for determining energy consumption in larger scale operations.
It’s a bird! It’s a plane! No, it’s SuperResolution! Okay everybody get ready for some science. Testo SuperResolution is a fascinating and extremely useful technology that is patent-pending and available on Testo Thermal Imagers.
Amprobe AT-2005 and AT-2005A are no longer manufactured.
In many industrial places, hospitals and large buildings electrical circuits run in metalic conduits. It’s a great way to protect cables, but when it comes to tracing them behind walls it might be an impediment, as such conduits tend to depress the signal. The only way to trace wires successfully over-and-over again is by using wire tracer with signal booster.
In the world of test meters you want to get the most bang for your buck; lots of features and high performance that still fits your budget. Dave Jones of the popular EEVBlog recently put a group of multimeters in a similar price range (Extech EX330, Amprobe AM-220, Elenco M-2625, Global Specialties Pro-50, and Vichy VC99) to the test and one meter came out clearly as the top dog. Drum roll please… Extech EX330!
