About

We help people buy used bench instruments without getting burned. Name the one you’re after, like a Tektronix 2465B, an HP 34401A, a Fluke 87V or a Keithley 2400, and there’s a page for it. Each one tells you the model’s story, its specs, the options worth having and what to check before you buy.

What bench users know about this gear is scattered across service manuals, datasheets, the TekWiki, repair threads and years of trial and error, and a raw eBay search gives you none of it. So we keep 30 model pages in one place, write down the tells that usually take years to learn (failed self-tests, lost calibration memory, blown input fuses, worn CRTs, missing options, a voltage selector set for another country) and pick the listings we’d buy.

We don’t sell test gear. No affiliate links. We earn nothing. We run no analytics or tracking cookies, and we’re not affiliated with any instrument maker. See how we work for how the pages are researched and our disclosure for how links, picks and photos work.

Graticule is part of allbutnew, a set of shops for secondhand gear. Got test gear to sell? The “Get an offer” link on every model page sends it to our test equipment expert, who replies by email.
