Marameter | Self-centering inner measuring device 844 K Inside measuring probe models (split-ball probe) 844 K Standard for common hole shapes • Split-ball probe made of hardened steel • Hard chrome-plated measuring surfaces 844 KS split-ball probe for bore measurements close to the bottom of the hole • Split-ball probe made of hardened steel • Hard chrome plated measuring surfaces 844 KC for common hole shapes with DLC coating • Split-ball probe made of hardened steel • Measuring surfaces and inner edges coated with DLC (hard diamond-like coating) • Enhanced wear protection and very low friction coefficients, therefore • ideal for measurements in sensitive or abrasive surfaces • For common hole shapes Particular advantages of DLC coating • DLC coating (diamond-like carbon) • Extremely hard coating for very high wear resistance • Extremely low friction coefficient, thus preventing e.g. - streaking on precision-machined non-ferrous metal surfaces - increased wear in abrasive materials • DLC coating over entire measuring surfaces including inner contact point of driving needle, for very high long-term accuracy (Linearity) • Visual wear display: Visible light spot once coating is worn out • Excellent corrosion prevention Ideal equipment for long-term accuracy Driving needles are inserted in the probe to transfer the measuring movement of the probe head to the indicating instrument. To ensure maximum service life and thus high linearity in the long term, Mahr driving needles are usually made of solid carbide. Modular system When combined with extensive accessories (indicating instruments, inside measuring probes with driving needle, holders, extensions and right-angle attachments), inside measuring probes become precision measuring instruments customized to the measuring task.
