This is a bag of 100 pairs of tweezer test probe parts to build 100 complete tweezer probes for the popular EDS-88 series of CapAnalyzers from EDS. All you need is some RG-174 coax and a soldering iron. I will build one for you so you can copy. These probes sell for $29.00 at all EDS distributors so you essentially have the important stuff to build and sell $2900 of replacement tweezer test probes to either CapAnalyzer owners, or anyone that wants the best tweezer test probe on the planet for their DMM or competitive cap tester. This bag contains 100 pairs of beryllium copper tips as well as the 100 pairs of nylon tweezer handles that snap together. These are the newest probes that are actually marked "ELECTRONIC DESIGN SPECIALISTS" and not Pomonas or copies.
