History Stephanie Kwolekan American chemist of Polish origin, inventor of kevlar Poly-paraphenylene terephthalamide — branded Kevlar — was invented by Polish-American chemist Stephanie Kwolek while working for DuPont, in anticipation of a gasoline shortage. Inher group began searching for a new lightweight strong fiber to use for light but strong tires. However, Kwolek persuaded the technician, Charles Smullen, who ran the spinneretto test her solution, and was amazed to find that the fiber did not break, unlike nylon.

It starts by taking results from what was four different test modes and displaying them all at once — graphical wiremap, pair lengths, distance to fault, cable ID, and far end device.
The end result is reduced test time and technician error. That makes high-quality installations more efficient than ever. They have to rule out a whole host of potential cable and service issues before determining the cause of a connection problem. Is there telephone voltage?
Is there an Ethernet switch at the far end? That means faster, more comprehensive troubleshooting. This not only slows the test process, but also causes frustration and leads to high user error rates.
MicroScanner2 has defeated this convention by displaying key test results — wiremap, pair lengths, distance to fault, cable ID, and far end device — all on one screen. Plus it features an oversized, backlit LCD screen with the power to display wiremap results graphically, which brings unprecedented comfort and clarity to the user experience.
Multimedia Support Tired of losing or breaking all the adapters needed for testing the various voice, data, and video media types?
MicroScanner2 makes these awkward adapters things of the past with built-in RJ11, RJ45, and coax support.
Both the main unit and the far-end identifiers can be used to test telephone jacks, Ethernet jacks, and CATV outlets right out of the box. Just one more way MicroScanner2 streamlines cable verification. IntelliTone Toning MicroScanner2 features built-in IntelliTone digital and analog toning to precisely locate virtually any cable or wire pair, regardless of work environment.
Digital mode especially performs in environments with high data, RF, or electromagnetic interference.
When coupled with the IntelliTone Pro Probe, it can also be used to verify cable wiremap from either the tester end or the probe end.
These cables are optimized for lower frequency transmissions, and therefore are more easily isolated with a low-frequency tone. This provides technicians a decisive way to identify individual wire pairs before punching them down or when diagnosing voice transmission problems.
VDV Service Detection Voice, data, video technicians have a lot more problems to deal with than just the cabling. Detect the presence of POTS voltage and verify polarity. Or, confirm proper PoE voltage and pairs. MicroScanner2 features a rubber wrap-around holster that makes it the right tool for even the toughest jobs.

Kevlar is a heat-resistant and strong synthetic fiber, related to other aramids such as Nomex and pfmlures.comped by Stephanie Kwolek at DuPont in , this high-strength material was first commercially used in the early s as a replacement for steel in racing tires.
Typically it is spun into ropes or fabric sheets that can be used as such or as an ingredient in composite material.
