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 844 KC for common hole
made of hardened steel shapes with DLC coating
• Hard chrome-plated
measuring surfaces • 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
844 KS split-ball probe for
bore measurements Particular advantages of DLC coating
close to the bottom of the hole

• Split-ball probe • DLC coating (diamond-like carbon)
made of hardened steel • Extremely hard coating for very high wear resistance
• Hard chrome plated • Extremely low friction coefficient, thus preventing e.g.
measuring surfaces - 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.
