Micrometers
Outside Micrometers SERIES 102 • Standard analog micrometer. Thanks to a heat- insulated frame, it is resistant to heat and therefore delivers accurate measurement results. • Measuring faces: Carbide tipped.
• Tapered frame (behind anvil) for measuring in hard-to-reach places. • Equipped with Ratchet Stop for constant measuring force.
