The first time you soldered up a surface mount component you may have been surprised "these are really small parts!" and there's dozens of different names too! QFN, TDFN, SOIC, SOP, J-Lead, what do they mean and how can you tell how big they are? Now you can have a reference board at your fingertips, with this snazzy PCB reference ruler. Measuring approx 1" x 6",...

The jaws are plastic, so not good for hot metal measurements or when you need perfectly flat...

Discontinued - you can grab Solar Digital Calipers instead! Caliper rule? Tire tread gauge? Ruler? Thread scale? Writing instrument? The Messograf is all of these in one. It is a multipurpose instrument, constructed of chromium-plated brass for those who demand more than just the joy of writing. Many have tried to copy it - none have succeeded. This is the original....

The most useful tool we've ever laid our hands on. These calipers are really good quality and an excellent choice if you need something better than a cheap 'disposable' pair of digital calipers but you're not quite ready for a set of high-end Mitsutoyo calipers. These digital calipers work by having a capacitive sensor instead of a rack and pinion, so they never go...

The most useful tool we've ever laid our hands on. We thought we'd use them just for electronics but then we got our hands on these calipers and had so much fun we started measuring everything. They're indestructible - which is good because we don't know what we'd do without them - and ultra precise which is super helpful when measuring components or when trying to...
