I'm not a professional jeweler so I can't say how accurate the measurements are. Based on multiple measurements I took of several beads I own I would say they are fairly accurate. Needed to measure parts I'm reselling but didn't want to spend an arm and leg. Find this good value for money that does what it's supposed to.
