KELIBRON: caliper and micrometer simulator

KELIBRON is a free measuring lab that runs in the browser, with nothing to install and no account. The bench has vernier, dial and digital calipers, outside, inside and three-jaw micrometers, and parts made to real sizes. You measure outside diameters, bores and depths, read the scale yourself and check the part against its drawing. The reading and the pass or fail call both come from the lab’s measurement model; in the wrong-use scenes (a tilted jaw, a skipped zero check, debris on the faces) it gives no verdict and shows what threw the reading off. KELIBRON is made by Tealun. It is a teaching simulation, not a calibrated instrument, so its readings are not inspection results.
